leave Corypheus in that rotten prison was entirely possible,but of course the writers had to make an unbelievable and contrived outcome with Hawke releasing him just for fun of the battle.
If the Warden managed to imprison him in a so well elaborated way there was a good reason and only a moron like Hawke would have thought that it was possible to resolve everything so easily.
If the writers made the prison impossible to escape without breaking the seals, then it's simply not possible to leave Corypheus in that prison without simply staying trapped there along with him. You can't argue that it's possible based on what they could have written.
No character there claimed it would be easy, but more importantly, they had no choice. It doesn't matter how contrived one thinks the setup is; Hawke & co's only options are either fight their way out, or stay there and die. Whatever reasons the Wardens may have to force Hawke's father to seal Corypheus away are irrelevant at that point.
Exactly, they can do the same for Dragon Age. Ultimate sacrifice won't be a valid world state.
So you want to play a character who spends the entire game in a room with a war table? That sounds like a very boring game.
Meredith is nothing compared to Teryn Loghain. If DA2 Anders was in the Warden's party, the Warden would either keep him under control or kill him before he does anything stupid. Same with Isabela. If the Qun demanded Sten kill the Warden, he would try it and die during the attempt. Many people wanted to kill the Warden and they all shared the same fate. Sten is nothing compared to the Warden.
As for Corypheus, even if he did escape, the Warden would not rest until he is dead for good. The Warden always finishes what he/she starts and doesn't leave it to others to correct his/her mistakes.
Varric's only mistake was meeting Hawke. Everything went bad for him after he met the accursed Hawke. Defend Hawke all you want, it won't change the fact that he is such a lame character. I don't think anyone likes Hawke outside of BSN.
The archdemon is not just any dragon. The archdemon is a god and only the strongest and most powerful like the Warden can defeat it. As for powerful ancient elven mages, the Warden already defeated one remember? He/she can defeat Mythal in Morrigan's quest. Even Mythal knew she stood no chance against the Warden and gave a trinket to Hawke to save her ass. And when you say dirty work, are you talking about how the Warden decides the fate of their existence? Redcliffe would fall without the Warden. The Warden decides whether Elves or werewolves live/die. The Warden decides who will be the king of Orzammar. The Warden decides the fate of the Circle.
They could have done the same for Dragon Age, but they didn't. It's been 2 games now and the Warden's death is considered a valid option for the world state. It's far too late to retcon this part of DA at this stage.
I didn't say anything about playing the character in this role; I simply commented that the Inquisitor can still do this, and seemingly is going to do this as of Trespasser.
I don't see the point of comparing Meredith to Loghain, because my point was that the mage Templar conflict rising up in Kirkwall was building long before the Hawke family even got there. But it's funny that you mention that, because Loghain was a chump that, despite his accolades, failed to rally the people to him and had a civil war on his hands that he couldn't handle himself.
Obviously, any character that attacks the PC would die, be it the Warden, Hawke, the Inquisitor, Shepard, whatever. The point is that they'd still have to kill their so-called friend, just like the Inquisitor does if Iron Bull turns on the Inquisitor in Trespasser, because Qunari are simply not trustworthy.
Some people have a very selective memory of DA2's story. The first grave mistake Varric made in DA2 was putting any kind of trust in his brother, who, you know, betrays him and leaves him for dead in the ancient thaig. If not for Hawke & co. to help fight off the rock wraiths and find another way out, he'd be dead. I'm sure there's some sort of meta-gymnastics that could somehow make Varric's rotten family Hawke's fault, but I'm not sure how well one could stick the landing. Whether or not you like the character won't change the facts of the story.
The archdemon's greatest power lies in its ability to command the entirety of the darkspawn horde, and cheat death by passing on to another darkspawn should the dragon be killed. There's nothing to indicate that the dragon body itself is any more formidable than other high dragons. Every PC is perfectly proficient at killing dragons. The Inquisitor practically makes it a hobby. I don't see how Flemeth is really relevant, because any of the characters could have killed the dragon. Flemeth would still cheat her way out of death anyhow, just like Corypheus did at the Warden prison, despite Hawke actually killing Corypheus' physical body. Even if she killed Larius or Janeka, he'd just jump to some other blighted creature nearby and be on his way, which there would be a lot of where they were. Funnily though, here the Warden would be a potential meat suit and a liability, considering the connection to the Blight.
The only faction whose existence you really have any control over in its entirety is the Dalish. The Warden must do favors for either Harrowmont or Bhelen to get them on board, and losing Redcliffe doesn't really make much of a difference at all. You still have to fetch ashes to save beardy. With the Circle, killing the mages is doing the Templars' dirty work, and helping the mages is still doing the Templars' dirty work. Either way, the Templars are alive, so you can either get the mages if you save them, or the Templars if you purge the Circle.
