I know i'm not alone out there when i bust out the occasional "one-two step" in the battle room i've even dance with other people we even got our whole squad up in a dance crew and served some people... lol For real though i don't think it would take a whole lot to add a skill tree (that would require low amounts of sp seeing how it would be a useless skill in battle) that would be for battle room techniques. My first idea was a dance skill tree, head banging air guitar, hustle, air dice, or even some thriller. but thinking more about it there could be several actions you could perform with each skill you advance in a certain technique. there could be , a dance skill tree, a greetings skill tree, and then a trash talk or "taunt" skill tree. JUST IMAGINE the fun people would have just from being able to humpty around the room or flip off some people....
(side thought add the opposing team to the battle room?) huh huh.
i think this would totally turn players on and bring a laugh or to each time you prepare to deploy. It would give a whole new spirit to the battle room maybe even the game itself.

even after you put it in only cool ppl like me would play around with it all the serious sallys would talk trash and leave it alone.
you might get a few rooms full of newbs humping each other around the floor though

- give it some thought don't be lame and just view please post. I wanna hear your opinions on this.
