Regarding public games, sometimes I think "If I die X times, I should just leave". What should X be? Also, is that rule of thumb really a good idea or are there other factors to consider? I want to hear people's opinions on this.
edit: Alternative title: "When should you leave a public game to help your team?"
edit2: I mean this as advice for people to follow if they want to, NOT as some sort of kick feature to add to the game.
