i'm just dropping a brief comment here that if ALL healers grief you... i think the blame here is not the healers but you. most likely that "griefing" is just a healer mistake or panic heal.
if there is clear evidence this is NOT the case. you clearly done something that triggers people if it happens on multiple occasions.
if you need LD that often then either your healers are bad, or you as tank are bad. maybe even both. but i highly doubt that EVERY healer is against you when you pop LD. and i HIGHLY doubt every single healer you have in duties is so bad that you'd require a living dead to survive. i've had plenty of healers that were good enough to keep me alive despite the fact i had at times mitigated not enough.

Dark knight could use a small buff. or warrior a nerf. but in no way are the healers the only ones to blame for your misfortune. and given some of your previous comments towards people i can deffinetly see why someone would like to teach you a lesson in manners by having you die in duties. if you're in game writing the same way as you do here then i do not blame a healer to have a bit of fun with your toxic behaviour.
