Assassin for me too.
Trapper gets boring real quick for me. Fade, BoS, Cloak of Shadows and stuff are fun to play with but when the entire Martial Arts tree bar maybe two skills is just bugged and/or critically underpowered, I don't feel there's much else to do with her.
I did a hybrid between traps and that fire kick skill which was kind of fun. Expensive to gear though. Obviously wasn't too memorable as I can't even remember what the skill's called and I have sunk
way too much time in to this game
