Double blight anyone???

I don't think there will be a double Blight in Dragon Age 4, nor should there be. That game will already be dealing with some huge plots, from Solas' plan to bring down the Veil and restore the ancient elves at the cost of everyone else to the war between the Tevinter Imperium and the Qun.

Now they could set up some stuff so that that happens in DA5, but I don't think it should actually happen yet.

As for Fenris, since he can die in DA2 they can't make him plot-relevant. The most you'd get is him being in a side quest of some sort.

No blights in 4 at all, I'm just here to punch Solas with Fenris.

While I would like to see a double blight happen eventually, I don't necessarily want it to happen in the next game. With Solas and the qunari/Tevinter conflict, I think adding in something as catastrophic as a double blight might distract from everything else going on.

Awakening showed us that a type of "Blight" can occur even without an Archdemon being necessarily active. The Architect's experiments created two factions of Awakened Darkspawn that remained plaguing the surface, even after their brethren returned underground.

Legacy also mentions that following the First Blight, the Wardens encountered talking darkspawn that could command portions of the horde even after the death of the Archdemon, which was how they first learned about Corypheus and the other Magisters Sidereal. They further discovered that Corypheus (and possibly others) possessed the innate ability to "call" to the Darkspawn, much like the Old Gods do.

Lastly, in Inquisition, Solas raised the terrifying possibility that the death of all the Archdemons wouldn't actually prevent future Blights. Both in banter with Blackwall and during Here Lies the Abyss, he seems aghast that the Wardens are committed to slaying the Archdemons based solely on it's effectiveness in preventing the Blight in the short-term.

Solas: The Wardens see themselves the world's defense against the Blight, do they not?
Blackwall: Yes? Why do you sound so skeptical? Doesn't everyone know this?
Solas: When an Archdemon rises, they slay it. What will they do when all the Archdemons are slain?
Blackwall: Retire?
Solas: Without Archdemons, there can be no Blights. Is that the reasoning?
Blackwall: Right. Where are you going with this?
Solas: Nowhere. I hope they are correct.

While only speculation, this might suggest that without the call of the Old Gods to keep the Darkspawn preoccupied underground, the death of the final Archdemon would cause the Darkspawn to swarm the surface en-masse. Unlike the previous Blights however, there's nothing anyone can do to force them back underground, meaning that the Wardens and all Thedas would have to commit to slaying every single Darkspawn in existence to eradicate the threat once and for all.

That might not be a battle that anyone can win, meaning that the Wardens' attempt to save Thedas in the short-term, are unwittingly dooming everyone in the long-term. Hence the reason for Solas' rebuke that "the Blight is not something you can smugly outsmart".

But to answer the OP, I don't think the games should focus on another Blight or any Archdemon (or both) waking up centuries earlier than they were "supposed" to. Even dealing with another Magister causing trouble and/or a pseudo-Blight would be retreading much of the same ground that Origins, Awakening, Legacy and Inquisition already covered.

Not saying that we can't deal with Darkspawn or the Archdemons again, but the devs would have to do something new with them. Something about the origins of the Archdemons for instance would be a way to bring them back into the story, while doing something completely different than we've had before?

Well, considering the fact we still have 2 more archdemons to kill, I would be fine in seeing another Blight in a future game. But not in DA4, and not as a double...the next game should be strictly about solving the problem with Solas and his addiction with deconstructing the Veil, and maybe something about the Tevinter-Qunari war. A new Blight should only happen in the 5th game, and I hope that particular game doesn't happen until nearing the end of the Age of Dragon. This way, once the archdemons are dead, we can move onto the 10th Age. I honestly don't know who can fight 2 Blights at once, since 1 Blight almost destroyed Ferelden if not for the HoF and his lucky survival via Flemeth.

I hate the darkspawn and their cruddy taint. I'd much rather punch Solas or one of his Evanuris buddies, or an evil Magister. Darkspawn and Archdemons are boring. And please, no more recycled main villians like the Architect, that was a huge contributing factor in why I didn't like Cory. Fenris was cool, he is always invited to my evi-mage-slaver slaying parties.

Yeah a double blight on its own could/would throw us in as wardens again then we'd have the age old argument "i wannae be my hof" etc etc so no thnxz.

I prefer freds basic take of the ultimate threat that basically unites all the factions, possibly have us fail on stopping solas from tearing the veil down but the consequences are, per usual, not what solas believes them to be. The ultimate threat, although overly used, seems the best idea to handle Tevinter an the Qunari, it would just need to be done with care, be well thought out an obviously no suck which bringing down any of these nations single handedly would, not to mention having a pc single handedly stop solas would suck an imo be laughable

Solas first, then a double blight in order to find a way to wipe out the darkspawn threat once and for all.

You're right.  Unresolved plot thread that needs to be tidied up.

Good.  Don't get me wrong, I always keep Leliana alive and loved her in DAI in particular.  I just want the presence of whoever to make some kind of sense.  Do like what was done in ME3 and hae replacements for dead Tali, Garrus, Jacob and Jack should they have perished in the Suicide Mission.  I actually think the role Leliana had in DAI was more significant than any of those in ME3 but it would be best to avoid those situations.  Though, as you said, that's the plan.

I'm more interested in the Qunari-Tevinter plot tbh.

And I would rather have seen Red Lyrium Fenris in the Bad Future.

I don't think there will be a blight in Da4, but ì do hold the fantasy of one of our protagonists(da4 or no) finding an uncorrupted still imprisoned old god, talking to it and then choosing whether to leave it in it's prison, kill it, or set it free. Then have which choice you make affect a later game about the blight, which will either have 1 arch demon, 2 archdemons, or help from an old god, depending on the previous pc's actions.
