One set of changes I would support in this regard, because I think it would be better and more competitive gameplay, not because it would be an extra advantage to anyone in particular, or any situation:
1) make the number of attention points a team gets static and constant, say 120 regardless of scholarships, because everyone has the same number of hours in the week; and
2) diminish the value of all APs after unlocking recruiting actions for a recruit; and
3) negative value for pestering, you start losing credit for bugging a recruit with a bad preference match
I’m not in favor of specifically changing any of the preference parameters, or increasing the division bump. But I do suspect this change would make it harder for teams to overwhelm via AP.
