Am I the only one who thinks URF should be a permanent Game Mode?

I love Ultra Rapid Fire Mode and I enjoy it with a lot of friends.It's very fun to play and it doesn't take a lot of time.I really think that Riot should add U.R.F. mode as a permanent mode,because a lot of players are logging in just to play URF.That way Riot could have a much more players online than before and we could have more fun.What's your opinion about U.R.F.?
