All Random U.R.F defeats what U.R.F is about.
TL;DR It kills the fun and balance.
1 team tends to get a team full of OP champs and the other team might get 1-2 OP champs and 3 mediocre resulting in a one sided slaughter fest.
Playing champs that aren't OP is now a gamble and that makes it worse for me, when I play U.R.F I would always take the unconventional champs and try and make them into something special or try new things with them. Now if I get Zed I am stuck with him or have to gamble my one roll and I get....Velkoz..Nice.
I have an issue with the fact I can't go bot with my duo and play a neat combo like Poppy and Vayne for wall smashing or Nautilus and Blitz. I just feel like it limits too many options and also creates an unhealthy game play in which you are stuck with unhealthy champions and stuck playing against them as well. Atleast before you could have a zed on either team or a lux. Now one team has them and that team usually wins.
could be on either side.... I don't recall it ever not being blind, but my memory is bad. Oh well. I'm going to play another game of ARURF soon.
