The Tevinter Qunari War

Yeah thats a lot more interessing than another save the world story. I really don´t care for the Solas plot. We all knew that he´ll stop in one way or another.

Hmm, maybe I should revise what i said. I like the idea of dealing with Qunari and Tevinter politics as big part of the plot. What I don’t want is the resolution of the war being a plot point. Maybe it’s just how BioWare handled the Orlesian war and the mage Templar war, but I don’t really trust them to handle that well. So while we can take part in some big events of the war, I’d rather the resolution waited until after Solas was dealt with and likely not even until another game.

I can actually see that happening in my preferred scenario, though it would be more they agree to stop fighting until Solas is dealt with and resume immediately after.

but Solas isnt another Cory already. I prefer to think of him along the same lines as TIM. A morally gray allied character who does risky things in the name of the 'greater good' that then becomes an antagonist.

The problem is that while TIM was a very juicy character to have as your friend he went full mustach twirl in ME 3. How they solve that problem where Solas is concerned I am not exactly sure. I think giving the protagonist a personal stake against him or some kind of connection is the way to go but what that is I can only speculate.

Having not played the game yet...obviously...I cannot tell you what the 'point' of said story would be. The point of the story brings up thoughts of a story's theme or moral lesson.

First of all we don't actually know that we WILL stop him. Maybe he will suceed, maybe he'll fail, maybe he will try and only partially fail or try to stop himself at the last second only to partially suceed? Maybe whether or not we stop him is tied into the war with the Qunari in any number of interesting ways? Or maybe he'll suceed and it won't be as bad as he claimed (or maybe he was lying?)

Second the question for me is not will we stop him but HOW will we stop him. Yes they could go down the generic mustache twirling 'end boss' route where we have some cliche fight for the fate of all exisistance and then he'll be just another TIM or Cory in the end or maybe since he is literally one of the most powerful beings in Thedas that fighting him will be impossible so we will have to talk him down? Maybe it will be one or the other depending on the circumstances. There are ways they could go do this and most of them I think are legitimate. They could tell a great story with a great cast of characters and great antagonists or they may not and we'll still probably get a great game anyways.

If we are a new protagonist he absolutely is another Cory.

Yes, it is really that different if the hero knows him. That connections changes the relationship from simply hero tries to stop villain from destroying the world into something far more interesting. The Vader/Luke stuff wouldn't be as interesting if they didn't have a connection for example.

It doesn't change the plot as a series of events, but it changes everything else. Context, motivation, etc. To use my earlier example, you think nothing in Star Wars would be different if some random Rebel who had none of what Luke had with Vader was the one to face him? 
Details are what make a story unique and engaging. Every kind of story at its most basic has been done before. The kind of stuff you want has been done to death just as much as the stuff you don't want. 
At this point I think you're just arguing to argue. Fact of the matter is Solas will e the main plot of the next game, so you'll just have to accept that. 

Not really. Trespasser already almost completely eliminated that possibility if we continue as Inquisitor. 
If they go with a new PC, then it reverses and it is all but certain that it will be Cory 2.0 or at the very best a watered down version of the potential Inquisitor had. 

Honestly Cory's motivation and backstory were just fine...fun and engaging...where he suffered was on screen presence and presentation. Namely the fact that he was A. muhahaha on screen, or B. a rage monster. I quite liked Corypheus but only because the lore portrayed him one way and...honestly the Inquisition just got lucky/ Divine Providence. With his talents and mind he should've squashed us like a bug (and nearly did). But we got lucky.

Anyways back to the matter at hand that is what BioWare needs to look out for no matter which of us is right on the whole relationship between the Warand the plan to stop Solas. We need nuanced characterizations and to give them screen time. Best BioWare antagonist might just be the Arishock because they actually gave us time to get to know him...in and out of character.

Hasn't the Tevinter-Qunari war been going on for centuries? Didn't Sten and Iron Bull fight in it?

As far as the hero needing a personal connection to the main antagonist, I would argue that's become a cliche all it's own. As if the protagonist, through their own ordeals, could never develop any understanding or even empathy for a foe they've never met. Luke wanted to save Vader because of Daddy Issues, but how much more heroic could it have been if it was stranger who genuinely believed in redemption for all?
