URF has never been about balance. People need to get it out of their heads. Its meant to be broken, its meant to be retarded, its meant to totally bust some champs and utterly fk over others.
Think of Ryze, Yasuo, and new Evelynn maybe. They are crap in URF since they damn well are URF like normally.
Thinks like Nasus, Ashe, Alistar, Amumu and who knows what else are absolute monsters because of it.
And people seriously wonder why Riot rarely does URF. People bitch about it. People complain about when it comes out, then people complain its busted, then people complain that it needs to go away, and then people complain why it goes away. People need to seriously shut up. Sometimes I wish LoL was a subscription game since that sure as hell would remove the majority of these complainers and it wouldn't cost Riot much since I doubt most of them even spend RP really anyways.
Also ARURF has ALWAYS been about who gets the better team? What is so damn different now? If you get a team of crap? You lose, move to the next game in 15 minutes. You get a godly team? Enjoy your 15 minutes of domination. Get a fairly even team? Enjoy a game that could last 30 minutes. When has this ever been different?
