I still prefer vesperia's battle system as it's more reminiscent of a fighting thanks to the 2D plane for fighting. The overhead 3D in Graces F made it feel less like a fighting game and more like a basic action game with combos. It's not to say it's bad, but I enjoy the fighting game style over the action game style, especially being a fan of games like Marvel vs Capcom, Tekken, and soul caliber. My fighting game appreciation hasn't died over the years, I just don't play them nearly as much as rpgs.
Oh yeah, I hated graces F's CC shit for limiting attacks, and the constant upgrading weapons to give you CC to get around that limitation. Even after getting around it, it was always at the back of my head to conserve CC for big attacks, which resulted in either me comboing for a straight 45 seconds or running around for 2 minutes waiting for an opening. It's a pet peeve at best, but it had to be said.
