I love when groups yell out requirements like that- they are basically screaming "I'm going to be a little bitch through the whole run, so be prepared!" =D

Those people are the same ones who have complete nerd rage psychotic meltdowns when someone misses a mechanic. I'd rather find out who they are BEFORE I get into the group than after. If my run takes 5 more minutes with normally geared people, but I actually have fun, then I'm all for it
