It's been said multiple times already, but I would like the enmity system in the game reworked so that a tank job can actually tank. Paladin is near worthless aside from solo or extremely specialized situations. With a new tank job coming out in the coming expansion, it would be nice for it to not be worthless right out of the gate.
Also I would like for the rampant cheating at Neo-Nyzul to be taken care of >.> If this is not doable, rework the battlefield so people can win without having to use cheats.
