I saw a comment on reddit that i think would be really healthy to bring URF back (not arurf)

Make it so that once you play x champion, you can't play that champion for another x amount of URF games.

Would help deal with the people who spam the op shit rather than just enjoying the gamemode.

Imo:

Once you play a champion, if you play them again within the next 5 games you are "locked out" of them for the next 10 games or so.
