And if the threads on here are any indication, there seems to be a fairly decent amount of 5 to 3 crossovers (YE and GP, SE and Coed 3, SSX and 3lite, probably more), it just seems very unnecessary. It's part of the reason why I never have and never will be a big CEA fan, though I'm sure they don't care. Until there are rules against it, they will continue to do it, they just might have less teams at the Summit this year.
I would be very curious to know how many teams they would have if they had 0 crossovers, I feel like it would be drastically different than what they have.
