And this matters why? This is why I use an addon that blocks the entire raid chat, so I don't see it. I also have chat bubbles turned off. I can't stand these people. Wiping in a 5 man in vanilla over 50 times was standard and accepted. Now wipe 1 time and everyone rages. It actually makes me sick people think and get mad over this. Failure is a good thing.
I know what you are thinking "Oh but It is LFR, you shouldn't wipe in LFR" - well news flash, not everyone can and will be as good as everyone else.
