The thing is, pyrokinesis have a strong resistance to fire, etc unless you release to much energy(which you should not be doing). Also, crazyness is not only a side effect of umbrakinesis, if you don't have proper control over your abilities, you can go crazy no matter what it is. A side effect furthermore are the effects that are NOT the effect you want.
