"Am i the only one..." No.
40% of the threads about ArUrf are "old urf was better,with this new random there is no fun"
other 59% is "where is it comin". the last 1% are the good threads (like yours) in which,doesn't matter if ranting or holding an argument in favor of ArUrf, there is actually a bit of discussion possible.
Now,sorry for that,but i hate it when a topic comes back again over and over,as i said your thread does give discussion and so we shall do that.
I prefer ArUrf because,being it a RGM,i wanna have fun no matter what happens,i don't care if the enemy gets a sona,as long as i get to have fun with my permagassing singed,it will just mean that i've lost a match of a mode in which that thing doesn't matter at all. In fact,when i don't know what champ to play or when i need to de-tilt myself and i can't find anything good to do so,i go back in the game queuing up for Aram,because there i can actually fuck up a bit without having real consequences (obv i don't troll or int,even against bots that could come with problems) and i can relax and i don't have to care about choosing a champ to play,i just want to play a bit,muting everyone's pings too if needed since in Aram there is no baron to care about. And the same applies on ArUrf,at least for me: Just gimme something and i'll take care of myself.
I wouldn't mind original URF,but as Sarutobi said it would lead to people flaming just so that you would choose what they wanted you to choose to have their easy win and brag.
But i also get the problem you and others talk about: The banned champs are now avalaible,so i thought about a thing: If the problem is only about the OP champs,then give the 6-way ban and after that phase goes through,give 2-3 random options between the champs the summoner has avalaible,and it will have to choose between those. So you can actually get to have fun and possibly win even if you don't get kissed by luck.
