70 war here. Dungeons definately arent as smooth as before but its doable. Have both ex primals on farm tanking in pretty much full deliverance making use of shirk and shadewalker aggro isnt a problem, and we have more cooldowns than before so I actually think we are stronger in a MT raid setting now with the proper support rather than being delegated to only OT. The content is pretty easy atm though so I wont make a judgement on overall tank balance until I see the first raid tier, my only gripe is shake it off being worthless and onslaught/upheaval using BG when the other tanks get those skills for free.
