I do agree that it's very tough on MNKs since you have to get GL3 for full damage unlike other classes - outside of Axe Kick and Perfect Balance it'll take time to build that up and if you don't stay engaged then you lose it fast. But I think their role changes slightly from PvE to PvP, i.e. they seem like more of a Swiss Army Knife to me. When I play Monk I don't care about topping the damage charts, I care about assisting my teammates and winning skirmishes. If my BLM can out-dps me then that's fine as long as I can pressure the healers enough so that BLM can nuke their target. Focusing solely on damage is shortsighted in my opinion.
