I am an Anders lover I really am *i'mforeverteamFenristhough* I am one of the fans who was really bitter with how he became a sassy, almost alistair clone *downtothevoiceactor* light hearted fellow in DA: A to a whiney little... well, pussycat. Seriously, it made me so sad because Anders from DA: A is literally a completely different character than who appeared in DA2, despite this I liked him still for various reasons. I do agree with an earlier poster that I would've been fine if he retained more of his previous representation and slowly descended into madness as acts progressed.
I don't know, Anders was just a huge turn off especially by the end of the game when he does the big bang and innocent people die. While I personally didn't like the Grand Cleric, I agree she was a bystander, but seriously, there was more than just her in that Chantry. And it just amuses me that he's always trying to clear the slander placed on mages when he did everything in his power to do otherwise. I roleplay when I play DA and being a Mage Hawke I was so flipping pissed when my lover not only lied to me but basically made the world hate me even more just so he could "make a statement" and all I could think about was "Man I knew I should've stuck with Fenris". Seriously it bugged me so bad that they made him in such a way. While I respect your opinion of still liking him after blowing up the chantry I can't help but to resent him for making the Mage situation that much more dire and adding more flame to a sensitive issue. Especially when I was a Mage who was actually trying to redeem mages in the eyes of others. So that's why I took his action seriously. And in my first playthrough I ended up killing him even though he was my romance at that point. From my perspective there was no way that Hawke would forgive him for such action and lying to him was an ultimate sin to the character I created for Hawke *diplomatic*. So it was pretty heart wrenching for me.
And then when I played another playthrough and romanced him again and spared him I was irked becuase he doesn't even give you a seedy kiss before the final battle like Fenris does xDD I mean come on Anders, I spared you and we're mage fugitives together now, you think I'd get some passionate smoochy smooch.
I love Anders, and I also love to hate Anders. In any case however, I'd love for him to appear in DAI especially considering that the choice of killing him or sparing him was one of the very few important choices the second game had to offer, So I better see some consequences if I'll be damned for either killing him or sparing him. So I do support the return of Anders. Especially because I absolutely adore his VA :3
And while we're at it I hope we get some Fenris too
