We made our first attempts on Vashj this week. We tried her 4 times before calling it. We did horrible the first two times better the third time then horrible again.
We got 2/4 shield generators the third time before the stalkers got us. The stalkers seem to be where the issue is. We have a warlock kiting, but he is having trouble keeping threat up, I'm throwing in frostbolts to help slow them down, but eventually one wanders away and starts fearing and it blows up. Any suggestions? Should I go full frost with points in perma frost to slow the stalkers down even more and have the ranged frost nova with the elemental? I'm raiding as 40/0/21 right now.
