Yah, I can handle tank or tank+1 dd, but it's the myriad combo of stuns/debuffs from multiple people that usually does me in.
Miasma for the slow debuff? Iirc Bio applies one as well, at greater range.
I do slot BlizzII, will try to use that more.

Hiding might be okay at the start, but it's not really a feasible strat given that I need to keep people alive, and any competent team will be looking to lock me down + prevent that.
Like, if healer making herself scarce? Turn around and molest a squishy dd instead. At some point healer will have to get in range to avoid imminent 3v4, and then sleepytime ensues.
