URF, One for All and Nexus Seige.
Ok. People have requested URF to be permanent and etc. No, I believe that you should have two rotating gamemodes or a custom game option of our favorite modes. Keep your All Random URF, but allow custom games to have normal URF. Dual rotation modes is what I mean. You'll have your normal rotation and a Twisted Treeline rotation. AKA: Nexus Seige in Twisted Treeline while there's Ascended. Putting these modes in TT allow more choice and those who prefer a lesser played mode are put against those few who play it too. Example: A 3 v 3 is better for those who prefer Ascension over Legend of the Poro King, and spices things up with lesser players.
