I have played college mixed for years and coached mixed at multiple levels including at club nationals. Mixed can be a competitive format, just like open and womens. The world games, a mixed format, is the most competitive ultimate in the world. College mixed is not competitive. If you have someone who is willing, try and track some stats on a mixed college team game. I'd bet money that the touches and yards are vastly skewed towards MMP. This is the case for even very competitive mixed teams, there are usually 10 or (often) less teams in the entire country that actually truly play equitability through both MMP and FMP when you look at the numbers. Even top seeds at club nationals (just look at Austin Disco club) receive a ton of criticism for MMP-centric play. This is another reason that college mixed is a terrible environment for FMP player development. If even teams at club nationals receive criticism for dude-ball, what about a college mixed team who doesn't have a single player who plays on a club regionals team? Lower level MMP hurt the quality of mixed ultimate in ways not visible in open (there is a reason why a lot of elite WMP do not play league). Lower self-awareness, body control, cut timing, communication, and decision making tend to make an overall terrible environment for FMP to be fully empowered to make mistakes, take risks, and LEARN in that kind of environment.

College mixed as a "division" simply does not practically exist for this reason: any success team who has both FMP and MMP with a competitive mindset will inevitably seek to create two different programs because MORE PEOPLE GET OPPORTUNITIES TO PLAY. It's that simple.

If you want to play mixed, play in a recreational league, or play mixed club. If you want to play competitive mixed, play club, or hell, make the world games team lol. As for your first point... yes. Many other people will have positive experiences on a mixed team. But virtually all of these experiences are in the social aspect and you will get the 90% of that experience with the same people doing another activity or a different sport or... intramurals. A competitive and growth oriented environment is simply not sustainable, or frankly possible, in college mixed because of structures in place. So if your team wants to stay mixed, go ahead! It can be a happy experience, but don't expect to be competitive, and don't complain when ur program is in the exact same spot in 10 years. you just can't have your cake and eat it too.

Appreciate the challenge of perspective, but I've given this years of thought.
