Battlegrounds? No problem. I'm not sure why. The language and verbal attacks are often much worse there, and I know that's why many people stay away. But I guess it's more impersonal there and much more common. Maybe that's why I can handle it so easily.
It is definitely much more personal in a 5-man group. That's certain. It's not "you all suck," but "you suck, Laurel." If I'm really not doing well, there are better ways to tell me, obviously. More often, however, the blamer is the one with the problem. "Learn to heal!" -- says the rogue pulling the entire room while the tank is waiting for the casters to regen mana. "[expletive deleted]," he goes on to say. These experiences really bother me and I just can't deal for a while.
