I think jutsu combination system (J.C.S) should be a thing... let's say.. i have fire element and someone has wind element we stand next to each other and then we turn on/click something... idk ... we use the 2 jutsus that can be mixed.. and then (fire+ wind) bigger fire. fire+wind= big fire wind+earth= dust (like a dust covered area (like the mist hing))
fire+earth= lava fire+water= steam water+lightning= electrified water (stun) water+earth= mud we can even do 3 ppl at a time example fire+fire+wind= huuuge fire o-o this way teams would be a really good thing to have.. if u ever get in a fight ... ur set etc.. etc..
