Oh, I am not going to adopt it as my power, because any way I can think of to make it work slightly, it rapidly explodes into way too much goodness. If I even have very slight direction control (say, within 300 degrees or so), it is just too easy. Without direction control any action becomes part suicide, so I guess I could only do lose-lose attacks. :P
What I find fun is thinking of more minor powers, and using them smart (in this case just make things that make fire). :)
