a High level ranged rogue paired with the right gear does CRAZY DPS.
Not impossible for a ranged rogue to crank out 600 damage in 5 seconds (though luck is a big factor). especially with a tank. hell even at 800 might be possible.
I once did 450 + 450 2 hits in a row with melee rogue.
rogues are very burst and big on set up great boss killers. but falter comparative to warriors when dealing with crowds. kind of high risk high reward gameplay.
