I think I'd prefer Physical, Social and Mental to Force, Finesse and Fortitude. While Manipulation might overlap with some bits of Wits, I dont think Dex overlaps all that well with Manipulation. Likewise Strength =/= Charisma =/= Intelligence. I guess it puts more emphasis on Abilities, but I struggle to see why a high Force bruiser type should also be better at Charisma, just because he's also Strong.
