People made URF unfun.
Playing URF is not about fun anymore i guess. Every team i play with or against, are not trying to have fun but to win as fast as possible and as boring as possile.
I dont want to be playing URF and suddenly, enemy team 5 man push mid and go for the win. I dont want to play URF and be worried about a guy splitpushing alone and taking turrets alone while everybody is fighting.
And i dont care about losing games on URF, but winning like that, is not fun for either team. The only thing that you're playing if you do that is "Lets see how fast i can kill turrets + nexus".
