New Belt is Screwing Up My Stealth Openings

The new belt is screwing up my stealth openings in M+. Tank charges to the next pull, I restealth and then the belt fires off a lightning bolt and I get pulled out of it. Bad enough I can't restealth when tanks are chain pulling, now even if I can, I still can't get a good opener. Oh yeah, the lightning bolts love to pull mobs in from Narnia, too. So now my stealth is about as good as an Arcane Mage's.
