Fragmenting your moveset over levels is just dumb. Score-based games require the moveset to become second nature. Having a changing moveset, and something so basic as a revert being the changing factor, doesn't help this.
I'm sure people will learn to adapt and all; it's just really inelegant.
Personally I think THPS3 moves should stay in THPS3 period. Same with 1&2, you shouldn't able to manual on 1's maps, but from the looks of it that is exactly what they've done.
