I'm perfectly okay with a DI and a DII worlds.
Take, for instance, NCA College Nationals. My school, Providence College, is a Division I school for all sports, but we do not have football. We also have a total of 3,700 students. Until the All-Girl D1A (D1 schools that have FBS football are "D1A") and D1 split occurred in 2010, we had to compete against schools like Louisville and Maryland. My Friars, are, God love them (pun intended) never going to be at the level of a school like Louisville or Oklahoma State. Period.
While it's going to be a tough pill to swallow for some gym owners--which is not a bad thing--some gyms are going to be Division II gyms. This doesn't mean they're terrible gyms. Take Elmira College: they're a fantastic DIII school, they've got 1,200ish students, and they've got a talented cheer squad that places well at nationals. Could Elmira beat Louisville all girl? Probably not, but they also don't have Louisville's 22,000 students to choose from for a team.
