@Loonook: "Breaking" someone is never the answer. People who feel the need to "break" others are often the problem. In fact, gamers from older generations feeling the need to "break" members of younger generations is a huge cause of the generation divide. One of my writers runs the RPG society at Princeton University, and he says that the younger players are far more mature, but the older players imposing their style of rules-intensive min-maxing of characters and situations is often game breaking. When the younger players ask these other players to step off, they get "broken". This kind of attitude will drive away the younger generation, and then the hobby is screwed. Besides, it's just immature.
You wanna deal with problem players who are immature? Treat them like adults. Have an adult conversation. They can't handle it, you deal with them like adults, and politely ask them to leave.
