Just to confirm, I submitted a ticket to find out and got the following response, confirming that the Wants Success preference does not update between RS1 and RS2.
Me:
Based on my own experience and feedback on the forums, it appears that, unlike all of the other preferences, the Wants Success Recruiting Preference doesn't updated between RS1 and RS2 based on changes in prestige. Is that the case? If so, is that intended, or is that a bug that you plan to fix?
WIS:
That's correct, because it's based on the past four seasons of your team's success, excluding the current season.
