1 Hit for over 1k dmg... Look to Wizzy or Assassin(possibly good ranger) and nowhere else.
Monk, however, is much more favorable than these classes for PVP in many respects. Just because nowhere on your screen does a 4 digit number appear doesn't mean you arn't doing the damage.
Monks are at their best with duel weild, extremely fast, decent proccing weapons with haste on and spamming every trick they got. Once a monks up in your grill, your pretty much stuck there for a good 15-20 seconds, much of that time unable to melee and almost all of that time unable to cast anything.
Furthermore, while Monks/Bruisers are by far the scrawniest of the Fighter archtype, they're still high on the food chain, higher than any scout and MUCH higher than that Wizzy.
So instead of that 1000 damage in one hit... think...
90 180 110
340
450
400
120 120 100
150 80
150 80
150 80
150 80
150 80
180 100 120
in about 4 seconds... it's fun =)
