I didn't read it anywhere, it's my understanding from playing the game. I think your expectation is based on an interpretation of something Seble said, which is probably not what he meant to imply, that is that the criteria for determining success at each level is the same. The weight given for each category can be the same, but they can still have different criteria for establishing those categories within each division. I'm almost positive that's what he meant, based on how 3.0 has played.
A D+ D1 team can be neutral for "wants success" (that's CSUN, for example). I don't think that's true for D2.
And anyway, wouldn't that be good news, if your primary concern is the prevalence of lower division "superteams"? This feature is one thing that mitigates that concern.
