I think that the best solution for URF is to have different queues

Just my 2 cents about URF. The main problem is that you have 2 types of players: one who just want to mess around with troll picks and the other who want to abuse the OP champions. It can be solved easily with just having 2 queues.

One would be a true blind pick - full try-hard mode when you can pick all your Ezreals, Zeds, Shacos and so on. No bans, just a true blind pick

The other could be a "blind draft". Have a short ban phase, where each player bans a champion, or 2, even 3 (Yes, we have 140 champions, the mode would work even with 20-30 bans). I imagine it something like this: You have 10 seconds to ban a champion, then all bans by both teams are revealed, then you have 10 more seconds to ban another champ - boom. 20 champions banned in 20-25 seconds.

IMO they can be both open at the same time, or they can alternate - one week we have the mode with no bans, the next one - we have the mode with bans. Again - just my 2 cents.

Also - it should be opened a bit more often. I do like to spend my holidays with my family, so I do not really get to play the game around Christmas and Easter and having URF only these days really sucks for me.
