Sounds like people are saying go with warrior. Also warrior seems straight forward. Keep up your buffs and debuffs, and you get one big single target and one big AOE move per stance and mitigate or pop cooldowns as needed.

The Dark Knight stances and Mana cooldowns and dark arts and so forth doesn't seem intuitive. It seems confusing and a little overwhelming, on paper anyway. I doesn't really make sense to me and I figured I would need to play it to get it.
