Yes, it happends to me a lot too.

yes, sadly… it is quit anoying, and makes demology hard to play.
Doing your setup and stuff… but shortly before calling your Tyrant… GFG just died, for whatever reasons…
say byebye to your damage…

Hello fellow Warlocks,

I’m posting here to discuss an issue. US forums don’t seem to have a topic on this. My Grimoire Felguard keeps dying in dungeons. I suspect it’s either pulling aggro or dying to AoE damage. This is causing a significant DPS loss and is very frustrating. I tried submitting a bug report, but there doesn’t seem to be a relevant section on the WoW EU forums.

I’ve got logs as well. But can not post warcraftlogs links for some reason!
