Uhm, Rumbles only support 6 players at a time, offline. Online, they'd probably have a max of 6 players, plus 24 NPC characters.
I mean ALTOGETHER. 6 guys are on screen, but how many guys can you have waiting in the wings to join the fray before the server can't handle it? That's my question.
So you think the rooms will only hold 6 and the other 24 will be CPUs?
To avoid the problems you're speaking of, yes.
