All these battles I've seen involve tactics. it doesn't sound like its Narutoish to me. ANBU is just espionage and silence and shyt like that. So if you are referring to a ninja like battle with strategy than cool.
So the answer depends on what you might possibly have in mind. I remember a time when we battled for fun and to test ourselves a bit but all these battles are too strained and the set ups are completely ridiculous.
How about DBZ style battle?? I'd love to see that one.
