Alright I'll give a more serious answer: I give DPS players comms if it looks like they doing their best to play nice, wait for others to finish a cutscene, kill mobs and wait for others who haven't loaded or clicked on glowy switches yet.

Every once in a while I get players including healer who don't wait and just start sprinting off really far while someone or two are still watching cutscene or not here yet and don't respond even when asked nicely "X & Y are not here yet, hold up." -2nd and 3rd pack of mobs are incoming-
