Genuinely how do people enjoy URF?

I've given it a few tries now and every game just isn't fun. People reroll for champions with CC and then people proceeds to spam said CC. Or if not CC, they go for champions with extremely annoying mobility like LB or Fizz, etc. People just look for the cheapest thing to play as and choose that. Which ends up being extremely unfun to go against. I don't see how people enjoy this mode lol
