i dont disagree with SBing in dungeons, as long as you arent stupid about it. if youre running a lv 47(aurum vale) or lower dungeon, your il55 SB gear wont be met with hostility. if you are stupid, like the tank i ran ST with yesterday, and have il55 chest, head, legs, and feet, in ST, as a tank, the i will have problems with that. i let the alliance know, i let the party know. i figured it out because he died against scylla. while scylla is sometimes taxing on my mp, i have only ever been overpowered to the point that someone died my first time. so i checked his gear. we had him kicked before the next boss.

edit: all of his accessories were il100+, but in a place like that, SBing is unacceptable the way it was done.
