lol i hate the battle arena for the reason because it doesnt have fun but maybe with this new game thing it can be more fun i am with you tobi^^
No, it ruins the simple strategizing and stuff that goes on in regular battles. It will make it less fun, we are just making a forum version of dungeons and dragons(ain't that bad but as a forum no), and it shouldn't be choked with rules that suck the fun out of anything.
Also another point, what about jutsu's that have different effects, like those that are preformed a lot faster and are meant to have a high success rate and stuff, but are high of rank. And there are also jutsu's that sort of have the it takes time to be preformed and people can stop them from doing the jutsu, so in a way there is already a "failure" thing going on.
