Zestiria has a lot of issues (balance and the god forsaken camera), but the combat gets better once you reach a certain part of the game. It helps that I like to play more than one character though. The story is pretty meh, but I did actually enjoy the ending to it. I actually liked the villain, which is pretty rare for me when it comes to Tales games.
Have you played Berseria by chance? I find it’s a rather good game in the series. I dislike some of the characters or their particular tropes, but I think it’s not bad. The combat in particular is much better.
