I had this garbage the other day.
Tank says and then actually does drag the furbag miles away, we have to kill him there and then there were all the 85k adds to kill afterwards.
It's screamingly simple, you nuke him where he stands and everyone gathers on him at the end during unstable fuel to fry all the teddy bears who will gather round.
Only been forced to do that stupid other way once and it was a pain in the ***.
Or, maybe, you could y'know, use tactics, teamwork, and communication, and have the healer bring the adds right next to the wookiee as the channel is going off that indicates he's about to explode? You've got 5 seconds or more to get the adds next to him. All it takes is a tiny bit of awareness ..
