No Veil or Complete Veil? Which would you choose?

I like your theory and have been pondering the same thing.
If I remember correctly, the veil has begun to thin gradually for some reason. I would choose to let things stay as they are so that the veil will gradually weaken and dissipate completely.

I'd strengthen the Veil. All those evil wossnames lose their powers and optionally wither away to a horrible death.

Healing magic has already been replaced by potions, so all former mages could be re-trained as elfroot gardeners and alchemists.

As far as the technologically superior Qun is concerned I suggest trebuchet launched jars of bees (and a few wasps).

My choice is to remove the veil in a way that doesn't kill most of the races. Mage is my favorite class, so I definitely don't want a Dragon Age with no magic.

Bring down the veil and free the evanuris would be my choice.

Let's hope it doesn't come to that. However, we know that strengthening the Veil is something the Qunari were working on and if they see that as a solution to the problem of the danger of magic, I don't think they are going to give up on the idea. We know what Solas intends, although he refused to say exactly why it is necessary, but I think the big red beating heart may have something to do with it. So it is not beyond the bounds of possibility that we might be presented with such a choice.

I wouldn't worry unduly though. None of our other choices have ever really had a lasting impact, so there will always be a way to restore the status quo.

If it had to be only one of those two options, I choose Complete Veil since at least that option won’t kill anybody while the other will kill countless people.

I think this thread is asking the wrong question. Because I really hope BioWare has learned their lesson when it comes to ME 3 about doing this sort of thing and a veiless world versus a full veil world is way too diametric a shift to continue the story...if this comes down to the player it'll be the end of Dragon Age...or at least this plotline. Which is in itself fine I guess if they do that, but on the other hand that will rob us of the interesting story exploration that either option could provide if we were to do it in a vacuum.

So the question should not be what would we do as players but what BioWare's canon choice will be. And at the end of the day the choices we will make will regard around what will we do with Tevinter, the Qunari, and Solas...and maybe how we will prepare the world for a post DA 4 world...whatever form it is. To answer this question we need to look at the clues and the lore that Bio has been leaving up to this point and I thin I can see this going one of two ways:

1. In favor of a complete Veil- Yes Morrigan in DA I claimed that humanity was destroying everything in its path when it comes to the past and the pure world. Dragons, magic, etc. And while some of those things are certainly cool...or even benign...the question has to be asked though if its a good premise in its entirety. Afterall if the theme of Dragon Age is going to be between 'corruption vs redemption' then magic could be seen as the ultimate Corrupting source. Consider: Mages are easy to corrupt via demon possession, that in each one of the three games to this point we have been an accessory to a mage with an ulterior, hidden agenda...and in the last two games this has been a terrorist and a genocidal madman respectively. Consider also the history of mages. While this is not true of all of them...certainly...mages have grown to rule with a violent fist more often then not. The Evanuris, the first Tevinter Imperium, the current Tevinter Imperium, Avernus, and several other minor examples of mages using their power to force their ideology on others. Now of course we can debate whether or not this is a nature versus nurture argument all the live long day...but at the end of the day there is enough historical precedent within the DA setting where the writers might be saying 'magic is a bad thing.'

2. If the theme of DA is the restoration of the past world to battle the corruption inherent in the current system...then bringing down the Veil might be for the best since the Veil could be the original event which sundered the world from the magic. Afterall Morrigan seems to desire that outcome and it seems the current state of Thedas is about the constant encroachment of corruption...in the primary form of the Blight but there are others. We also have to take into account Sandal's prophecy in 2 'when the sky opens up the whole world will see'.

Honestly though if I had to hazard a guess...that sucker is coming down. When, how, and exactly what it will do when it comes down...hell maybe that will be a choice in DA 4 bringing it down so it kills off a very small amount of people.

Well, in this very thread, Hanako's choice is entirely predicated on the assumption that pulling the Veil down will automatically kill a lot of people regardless. Solas and his plan aren't even brought up.

That is kind of true but we have seen 'Blight Magic'.  

I mean if you are referencing my long spiel up there my basic point is that:

Magic is a corrupting influence in the world whether or not that is Blight Magic, Fade Magic, Titan Magic, what have you.  All of these magical forms is either open to corruption by using them or people use them for corrupt and tyrannical purposes.  And the Blight itself...which is one magical source...is inherently corrupting.  The Blight has been shown to poison or corrupt everything it touches.  

Now I do stress I do not think this is the only course BioWare can take but one course they may take to help explain and expand upon the themes of the Dragon Age.  As I said I find it far more likely that the Veil will come down at the end of DA 4 or that we will get some situation that is more or less a continuance of the status quo rather the a full strengthening of the Veil to the point the OP suggests.  

Excellent excellent point.  

As far as the connection between magic and blight is concerned, while I am not a lore junky either and the OP can probably go into a lot more detail on the specifics then I, I do know of at least three solid pieces of evidence which suggests that the Blight can be used as a source to power magic...and powerful magic then that.  Now I think this could be very different then Fade magic...but there we are:

1. Avernus in DAOs Warden Keep DLC was conducting magical experiements on the Blight during his time in there...and I forget the exact wording of his notes, but reading through them indicates that they were being used to make his magic more potent (and you as the Warden can then chose to take advantage of the experiements which give you special abilities)
2.  During DA 2 Meredith is infected by her Red Lyrium Sword which then gives her some crazy ass 'magical' abilities namely control over the stone statues in the courtyard.  Not to mention some of the other more crazy stuff that was attributed to Red Lyrium in that game.  
3.  Valta in the Descent and her magical abiities.  While not by itself the Blight she was given magical abilities by being exposed to the Titan which then since Red Lyrium is infected Titan's blood...

Naturally I was making an assumption in providing the scenario because there is still a lot we don't know and whether this is because "spoilers" or whether it is simply the writers haven't worked it out for themselves is anyone's guess.

Take blood magic, for example. We have yet to be told exactly how this operates and where it draws its power from. DA2 was entirely contradictory in that its codex said it did not involve doing deals with demons and yet everybody gaining power from blood magic was doing deals with demons. The writers confirmed that an essential element is sacrifice, which some people have assumed means inflicting pain, but that is not necessarily the case, it simply means giving something to gain something. In other words, you give a bit of your life force (or someone else's) to gain power but that still doesn't explain why it gives you power. Then in Last Flight Calien speaks of making a "blind bargain", which is why the results aren't always what you expect, but it is never explained who you are making this bargain with. May be that is why it is essentially blind. Still, wherever it gets its power from apparently it is not the Fade because it was possible for Isseya to spot that he was getting his power from somewhere else. (This could be important with regard to the Veil/not Veil argument.) Also, seemingly related to this, why do battles and large amounts of bloodshed thin the Veil?

Last Flight is also important with respect to Blight magic. It was revealed in that novel that this is a definite thing. The arch-demon is drawing its power from an alternative source, which I have assumed to be the Void rather than the Fade. Also, Solas has a number of conversations with Vivienne about the source of Corypheus' power and the agree it is coming from three sources: Fade, orb and Blight, more specifically red lyrium. However, we have yet have it confirmed which came first, red lyrium or the Blight. Again, we do not know exactly how ordinary lyrium bestows its power, whether it is direct from the lyrium or whether the substance simply provides a conduit to draw off mana from the Fade. If that is the case, then may be red lyrium provides a conduit to draw it from another source, the same as the arch-demon did.

If this is the case, then since elven legend says Fen'Harel shut away two sets of gods, one in the Eternal (Golden) City in the Fade and the other set in the Abyss (Void), I have simply made the assumption that if strengthening the Veil will cut off the Fade to a greater extent, then perhaps it will also do that to the Void as well. Of course, the Titans do complicate issues. They are not creatures of the Fade and yet they have the essence of magic literally flowing through them, so strengthening the Veil probably wouldn't remove magic altogether but simply make it less obvious. It was also peculiar that the rise of human mages followed on immediately after the Veil. Why should it be that precisely at the time when the elves were losing their magic, the humans were gaining it?

Then there are Yavana's words in the Silent Grove that the "blood of dragons is the blood of the world" and that mankind in destroying the dragons were unwittingly destroying themselves. Of course that idea may have been superseded by the concept of the Titans or may be the dragons are linked in some way to them, so are of the earth as well, so the reason the Evanuris adopted the form of dragons was to signify their victory over the earth. Dragons do seem to go deep underground to hibernate and do apparently show a resistance to the Blight, so that could be another key to how it can be overcome.   

So may be there will not need to be a choice about the Veil and even if the PC made one, that does not necessarily mean it would pan out as they thought it would because there are too many unknown factors involved.

Whatever that prig Solas does not want is what I want. He wants to eliminate does he not?
