I have seen sooooooooooooooooo many potentially epic cannon defense gamed crash and burn due to noobs joining. It is one thing when someone joins trying to help, but when they simply refuse to leave, it literally can ruin the entire game. I think cannon defense should have some sort of thing where of all the players agree they can kick someone out of the game. Some sort of vote system where someone clicks on the person or the name and can send out a "kick out" message, and if everyone else in the game (except the person in question obviously) votes "yes" the player will be instantly kicked out. I just think this would make it a million times easier to get good cannon defense games. Who agrees?
