I have an level 33 assassin and I hated Zash's sugary sweetness when she talked to you, it just seemed like she was insincere and I needed to be on my guard around her. Things are totally different on my level 34 warrior. Baras seems more genuine in his praise and comments then Zash ever was and I think thats what I like about him. Granted I haven't seen the whole story yet, but to me so far Baras seems to be like a mentor/grandfather prepping you to take over his position either by you killing him, or because he's been promoted. I am interested now to see if how I feel about him changes as the story progresses.
