Please make URF a permanent game mode

After having this past (AR)URF up for as long as it was, I found myself wanting to solely play it. Going back to the normal game mode is now dreadful. I stop playing League for months at a time only to return once URF has come back. Its the only the thing that truly makes me want to play the game.

If Twisted Treeline and ARAM can stay as permanent game modes in today's age, then I don't see why URF shouldn't be one as well.
