I agree with noleaniml, in that I want to play a game that feels realistic, and the allowances I make on that preference are for instances where increased realism hurts playability.
I like the stratification in general; I like having the Big 6 conference jobs be the most prestigious, and the best platforms from which to compete for championships. I would like for there to be a "mid-major" level, from which a few strong conferences could produce perennial contenders, though at a lower rate than the Big 6. I would like the low levels of D1 to be a reasonable platform from which to ascend to higher levels with conference domination, and/or an occasional sweet 16 run. Mostly, I would like for there to be fluidity *within those levels*, and that's what I think was primarily lacking before. Getting the Duke job shouldn't shield you from having to compete for the best recruits. In the real world, when tarvolon turns Oral Roberts into a championship caliber team, he has big 6 programs competing for him; and sometimes big 6 conferences pulling those mid-majors in. The latter isn't going to happen, because conference re-configuration is probably never workable in a game like this. But the former should be true, and in any case, an Oral Roberts should be able to, after sustained success, achieve those top prestige levels without the conference dragging it down.
Probably the worst and most unrealistic aspect of the previous version of this game was that so many 4-5 star recruits went unbattled for, and so many of them agreed to be bench warmers for loaded-roster teams. In 3.0, you pretty much need to be willing to start all those top players right from the start. The premium is back on long-term roster planning, and day-to-day gameplanning.
