In this year's bracket the NESCAC can get 3 teams in the Final Four, but that would require upsets to happen. The exact same thing would still be required in your proposal to split up Wesleyan/Tufts/Trinity.
I think the NESCAC just got unlucky to have their teams ranked perfectly to end up in the same quadrant but they're still appropriately placed. The UAA was one spot away from a sweet 16 matchup had WashU or Emory been one spot worse. If Wesleyan or Tufts won a game or two more it wouldn't be an issue.
Ultimately I think the 1-16 seeding was done correctly and you don't. Agree to disagree.
