Be the better player and just leave after u die.
Trolls get no satisfaction if u don't put up a fight.
Leave, report.
If this was a PF/ pug group, just leave cuz there is no penalty.
If this was a DF party, just take the penalty hit and save everyone else the grief.
Cuz just leaving is much better than dying over and over again.
Also u get revived after an instance if u were dead now.
Looks to me like ur party got outplayed by a fussy tank.
