Dragon Age: Origins- Loghain. I never spare him, because doing that would do the Archdemon's work for him (supposed to be a brilliant general, and yet he's either a coward or incompetent). For NPCs, definitely Issolde- voice that makes "fingers across a chalkboard" sound delightful, deserves the murder knife, and hates Teegan getting any action.
Dragon Age 2- Sebastien. Not for his personality (I never use him), but because he overlaps with Varric. Tallis also is annoying. But the real hate is toward Petrice. I think she's a ******, but that would be insulting bitches everywhere. I want to ask her "The Qunari are minding their own business. Ask yourself why the church is losing members, and change that"
Dragon Age Inquisition- None of them really stood out (Bioware is losing what I feel is their strong point- character development). They are all flat and one-dimensional (although I liked Cassandra, Solas, and Varric- which is my mage party and Dorian wasn't that bad), but the worst are Blackwall (who seems to degrade Lelianna''s intelligence, she was with the Grey Wardens, yet she missed the fact that Al and the Warden were theonly two Wardens in Fereldan), Cole because a lot of what he says makes no sense. Sera is basically a walking toilet humor relief. And the worst of the worst is Vivienne. A "mages belong in the Circle, except me, who gets to be a noble and enjoy life" gets old real quick.
I've noticed a lot of hate toward Velanna and DA2 Anders (and Fenris and Merril). I thought Velanna was atleast justified. Sure, humnas weren't the ones who slaughtered her clan (this time), but considering Darkspawn are supposed to be mindless, is it really a surprise she blamed the wrong party, especially given how humans treat the Dalish?
Anders gets a lot of hate of what he did at the end of DA2. I actually supported that, to a certain extent. Grand Cleric Elthina WAS useless, Sure, Dumas was Viscount, but as Act 3 showed, he really didn't have much power. Elthiuna was the GRAND CLERIC, and the limit of what she does is tell Orsino and Meredith to go to thier rooms (and her Act 2 appearance is even worse "I'll deal with my stolen seal when it is appropriate." When it is appropriate is when Hawke told you. You didn't know it before (maybe), but now that you know, it is your responsibility. With an insane Meredith, a Grand Cleric not doing a thing to stop the crimes committed in the Circle (like Tranquilizing Harrowed Mages and removing any and all communication with the outside world), and a city designed to corrupt, what was Anders supposed to do? Remember, the Circles are prisons for people who committed no crimes.
I don't understand the hate toward Fenris. Sure, he's a walking pile of whiny angst, but if you were an abused slave who has no happy memories whatsoever, wouldn't you be one as well?
Merril is actually pretty cool. She's seems to be the one blood mage who realizes that blood magic is a dangerous, but useful, tool. She cares about her people, and is willing to do anything to help them.
