I assume that you won't see something silly like a fourth year against a first year. For balancing purposes, it'd make sense for the ones joining in the tournament to be separated by years instead of being an all-out brawl.

That way, RWBY won't get rolfstomped easily. After all, a lone member of CFVY can do what they can three times over.
