Draft URF
We all know how frustrating AR URF can be if you always get champions you dislike or that are no fun to play.
Riot could try out a Draft URF as rotating mode instead of AR URF, they could keep it for like 1-2 weeks and after the time they could do a survey for feedback from the community. The community could try it out and Riot would learn what the community wants the most!
In my opinion, this is a great way to gather feedback and learn about the interests of the community.
I have asked this in the player support yesterday and they told me to try out posting this here to see the interest of the community about this topic and the devs could measure the interests in such a modification.
