I don't know which class to play, although i used to play Monk back in time.
Note that i'm a PvP player.
Which one?
Rogue - Warrior - Monk
Rogue: I'm afraid of getting one-shotted by a random caster player. I love the way rogue acts in PvP's.
Monk: Pretty much good, a lot of mobility and survive ability but i don't like the way it acts. (Fists and mist? No... Not for me.)
Warrior: Super beast, fun to play but less self-heal. (A lot of people play warrior, i like unique things more.)
