Magic in Nanohaverse is too versatile, which is a good and bad thing.
Good because you can do alot of things and get away with it, bad because you can do alot of things and people would wonder why not just use something simpler
Like Teleportation for example, There's so many things you can do once you open up that possibility. Or large scale strategic elemental manipulation? That's always a party... Not good for whichever planet you're on though, but nothing says "
Fear us or else" like a class 5 tornado going 250 mph coming their way
...Okay, maybe that's not simple, but it's more creative than your sixth [Really colourful beam of light with a cool name].
