Ok, we went in today - and I tried tanking it on my barb for the first time. Both tries we did not manage - because tank failure (mine and the other followed soon after.)
All was good until the tank buster. Zariel got a proper posture - which got me into controlled state, all my keys were disabled... boom, one-shot. I find it kind of hard if you cannot use anything including block. That happened every single tank buster. (till the revive was no longer possible)
So... HOW can anyone survive that? People are supposedly running even MZ, so... how?
