43 hours in and im not bored yet. ive kiiiiinda been obsessing over the titles lately so a lot of those hours have been used through title grinding....which has lead to me being overpowered when it comes to the boss fights.
I'm only pushing 30 hours or so in Vesperia but have encountered the same problem. Grinding for materials for synthesis has left me a wee bit too strong. The difficulty balance is the only problem I've found thus far. On "normal" fights are way too easy for me at this point, but "hard" mode doesn't so much make the battles difficult as it just makes them lengthy and (after quite a few in a row) annoying to a point.
I hope the difficulty ramps up a bit (I just polished off the events at the colliseum with Belius after the desert, really cool part BTW!!).
I didn't play much of vesperia. Not that I didn't like it...it's just that I was half playing other games when I started it and so it took 2nd fiddle for a while, and then I just kinda forgot about it. Xillia may actually be the 1st tales game I end up finishing. 60hours in now ☺️
