I think this is the inherent issue with PvE games with PvP elements, Usually whats good for PvE doesn't translate well into PvP. It could either be a boss melter or a spitball gun. Then people bitch and the dynamics get changed and it screws up everything downstream.
Its a wave of buffs and nerfs, its really the only way it will ever be given the games hybrid nature. Just gotta roll with it.
