The issue is, if there is two divisions of 8 teams, with a 16 team A conference, you will be a very uneven schedule.
There will likely be a team that avoids playing M&D and Hero's while another team will ger them and also not play the bottom 2-3 teams.
If I were to take a stab at trying to even it up, I'd do it this way (you play all 7 teams in your division then one from other division). You almost need to put logic in building the divisions to evenly disperse the talent and SOS.
