What makes URF more enjoyable than the actual game

It's not the ridiculously low CD on abilities, sped up attack and movement speed or no mana costs.

It's how everyone can have (and usually picks) on a low cooldown. It makes for a much more interactive game both between teammates and with adversaries, and in the vanilla game would make it so the meta wouldn't be so fixed, making the jungle role not absolutely necessary for ganks and top something else than a lone island.

I am certain that the game would be much more fun if they kept this thing from alpha. I know it's just like the TP scroll from Dota, but I don't think diminishing player interaction for the sake of differentiating the game was a good choice from the start.

Also making it so the players have to walk from base to lane every back is boring.
