URF (Ultra Rapid Fire) Make permanent?

well ive had loads of fun playing URF and im sure plenty of other people have and ive also heard people saying to make it a permanent Mode, now I know what it could cause to happen less people play rank n other modes but just think now.. with twisted tree line and crystal scar? im not sure of how many people play those modes but in my opinion im sure not many do.. URF to me has to be the funnest game mode I could ever play.. just a thought as all :) it'd be really awesome if you would consider it :) (if u wish to reply and give opinions of what you think please do :)) but im sure over all A lot of people find URF fun... IM JUST GIVING A SUGGESTION OF HOW I THINK ITLL MAKE THE GAME BETTER
