Happens a lot to me, only yesterday i was grouping for a flashpiont with my mercenary healer, the tank of the group was a sith assassin, a pair of modifiable boots(heavy armor) drop i need, so does the sith assassin, they win the roll, i ask why did you need for them and was ignored as the tank rushed off into the next fight, i decide not to heal them so they promptly die. They ask why the hell did i not heal them....i reply why did you need on the boots? Again i get ignored as they rush off to next fight......again they die! They quit the group, we get another tank and all is good for the rest of the run The moral of this story......don't ninja the hand that heals you!
