A healer not healing and a tank not tanking is one thing, kicking a dps because they aren't doing the dps YOU want is abuse. There are people who will abuse parsing to the point where if someone even slightly doing 50 less then the rest of the group, "Your a scrub" and there the kick. That is abuse in my books. Someone doing slightly less and kicking them is retarded, someone doing a WHOLE lot less then the rest isn't. But since people can't treat a parser the right way it should only be given to see your own dps, not others.
