Wow...best announced feature in either game to date. But a couple of things:
1. I sincerely hope that this feature can be used in offline dynasties as well...if not, that's kind of a let down. I'd love to completely retool the entire NCAA, and carve my own way offline.
2. It is a little disappointing that you can't change the number of teams that a conference has, or add/delete conferences. One of the things I'd really love to do is to be able to set the number of teams per conference, and then set the championship rules. I've always wanted to have 10 conferences of 12 teams each, set up like the ACC, SEC, and Big XII, with everyone having a conference championship. Hopefully, this can be an additional feature in 2011.
3. Is this a one-time feature right at the beginning of a dynasty, or can you do it after every year? That would be super helpful in later years of the dynasty as certain teams become more powerful.
EDIT: I'm also holding out hope that this new feature will lead us to the announcement of a postseason customization feature, where we can finally implement a playoff structure.
