When people criticize me I just say things like "I'm RPing as an ice mage" or "But I never run out of MP when I cast Blizzards." Then there is the old standby "You don't pay my sub." Then when they bring it up again I call them an elitist and threaten to call GMs for harassment.

Seriously though, I don't typically get criticism but when I try to help people I usually get no response and the person continues doing whatever they were doing.
