I'm a noob to TF2, but I've seen on Youtube where its dodgeball on TF2 with Pyros shooting dodgeballs at each other Red vs. Blue. It sounds crazy fun actually since its all one shot kills i think and it would probably be the equivalent to a fight yard server on CSS. Just an idea

FWIW, very few servers that are 24/7 dodgeball are populated for a long period of time...
