I am guessing.. but Tanks take ALOT of abuse in this game. Tanking/Healing both are a step up as far as visiblity in party fails.. If somethings goes awry .. its always.. that healer sucked, or that tank sucked.. after hearing abuse alot.. you can dish it back or just choose not to take it.. as a new tank.. i used to always be dps.. i am still learning.. a duty or run.. i may not get right on the very first run.. but later will ace it.. I realize some guys run these runs/duties non stop and have like 30+ runs.. to my 1sit or 2nd.. but its always.. that tank sucked or something like that.. So I think the bad attitude is just a reflection of the abuse or bad mojo that was directed at them earlier.. I have to take the abuse until i learn the run.. but sometimes.. ya f those guys
