He's not as bad as I was afraid he was gonna be. By "not as bad" I mean he's not as OP. He's still easy-mode when compared to someone like Lann and is the most OP character next to Staff Evie. I can say, though, that I have never lost in DPS to a Kai of similar level, throughout all level ranges, unless I majorly screw up. And there lies one of Kai's biggest advantages, shortbow Kai is by far the hardest to screw up, which is why many will perform at least reasonably well.
