[b]WARLOCK is bad ass[/b]. Their supers etc. are awesome (Jedi/Sith like). I like the Hunters Hood/cape look though. I won't see myself much so gameplay wins over all for me. I'm bored with the knife since I've used the crap out of it in most FPS for years and years.
[b]Titan[/b] is my 2nd favorite for their super.
