Tales of Vesperia
Tales of Symphonia's 3D take on the Tales battle system was fun and interesting at the time, but five years on, it is feeling a little stale. And a stale battle system is about the worst problem an RPG can have, giving way to underleveled characters, and thus frustrating boss encounters. The incredibly long-winded story conversations don't help, either. Truthfully, I could not wait for my party to die just so they'd shut up.
