I only get mad at bad players when it affects me. It's one of the big reasons why I absolutely abhor enrage timers. Heck, it might be the only reason I hate enrage timers. I just play the game to get in there, kill stuff, and get loot. I don't care what someone's skill level is as long as they don't get me killed. But the moment you start infringing on my time and wasting it by dying or doing so low it triggers the enrage timer--you better be prepared for a talking to!

I don't even mind slow tanks/healers in 4 man duties. New to the game? Pull one group at a time. I don't care. I just want to play the game and not die. Don't get me killed and we all kosher. I don't care if it takes longer. I play to have fun. Pull slow!
