Everytime I see one of these threads I think, what would come in handy in a rampage in the real world. Raiton would be nice, but people can already control electricity, only a matter of time before you get killed. Katon is epic but once you run out of stuff to burn, your're going to have to fight. That leaves Futon, Suiton, and Doton if we are not considering kkg. These 3 elements are the ones we have the most problems with. Just think about it. Tornadoes, Earth Quakes, and Tsunamis. Doton is good unless you get contained in a place with no earth, but then again you can just spit some out. Suiton is same as Doton but where there is air, there is water. Futon is everywhere so I think it would be the most difficult to deal with.
