I'd just like to point out, several people are calling for nerfs lately. And sure, okay, game balance is important, alright, to a certain degree. But I also want to remind people, this is a DB mod. DB is basically the anime embodiment of overpowerdness. When you're a Z Fighter, you're kind of supposed to be a badass who can fight one-on-one with Eldritch Abominations and planet-buster level monsters. And yes, this is also a mod for Terraria, also true. But it'd be fun not to diminish the advantages this mod provides so much they don't mean anything anymore, either.
Sure, if it's really THAT op, okay, maybe, I guess it might need some de-powering. But at the same time, if a Kamehameha ends up being on the level of a bow and arrow and a Super Spirit Bomb deals the same damage as a grenade, then it sort of stops being Dragon Ball at all. Sometimes, fun doesn't absolutely have to be super challenging at all costs, and it's fun to eventually become somewhat op after working so hard and digging for weeks and wiping out dozens of bosses. Maybe it's a bit op, but when you worked hard to get there, it's also rewarding to some people. From what I've seen, getting the best powers this mod offers is actually not easy and requires some hard work and farming, as well as time and luck. I certainly don't mind when the rewards make up for the efforts put out to get'em.
My point is, if it's broken beyond belief, I guess it could be nerfed. But at the same time, let's not make the same mistake as many games who nerf the good things so bad they become useless. Let's not go from one extreme to the other and ruin it for everyone who love having that 'legendary Z Fighter' feeling we might get from this mod, and which in my opinion contributes to make it awesome.
tl, dr: If necessary, okay, nerf, I guess. But if not that bad, please don't, or not too much, because it's DB, which is kind of meant to be op, which is one of the things that make it fun.
