Ultra Rapid Fire Mode (U.R.F. / URF) !!

Riot's most fun rotating game mode in my opinion is U.R.F. so instead of waiting for really long times to play it why doesn't riot make it a permanent game mode? I once asked that to someone in the supporting department and he told that he couldn't do anything and If I wanted to see it happening I should create a post and get many upvotes so that riot developers can notice it. Although riot knows that URF is a really fun mode (because who doesn't like a low cooldown/no mana cost brawl after all?) probably they are not making it a permanent game mode because it creates a mess to their system. That's for them to know and decide. So if you agree with me give this post an upvote and maybe the day comes that I don't leave my pc to play URF all day long. Thanks for your time!
