AF1 is better than URF, and should be considered as a permanent game mode
Pretty self explanatory, It is my opinion that all for one is more fun and less stressful than URF. Much like ARAM it provides a low stakes arena where people can feel free to learn the mechanics of a champion they don't play very often as opposed to URF where everyone spams hecarim, Ezreal and Satan himself. I've even seen a team of bards absolutely destroy my team and I wasn't even mad about it because 5 bards launching their ults was just so funny to see. I think all for one would be healthy as an additional game mode, especially for new players who have a limited champion pool It would be a great opportunity For them to try out new champs and find their "main". It welcomes friendly competition and off meta picks, which I believe is important.
