Rogue Auto attack is half of what a monk puts out.
Our Bulk of DPS comes from Backstabbing (which is like a 4-5 second cycle) + clicking 3.0 every 15 seconds and disc daggerfall every 30.
While a Monk just needs to be left there and Auto attack.
Ranger just click epic every minute, make sure his atk/proc buffs are up and be left there to /autofire on.
By far monks require the least work, then rangers, then rogues.
but dps goes: rangers>monk>rogue if you leave them just to auto attack ;p
