We can now change our basic ki blasts to different charged variants (homing, bomb, powered up, rapid fire), but changing the color is still not a thing.Wait, I thought that was one of the new features in DBXV2? (Although now it occurs to me that I haven't really seen any traces of it... so yeah.)
I'm actually hoping for some pretty major changes in XV3 since they stated that it's going to get a lot more dev time than 2 had. Maybe they can shoehorn a few features in patches between DLC, who knows. They do seem keen on gathering feedback for the game, at least.
