The most fun I had playing LoL was always doing funny stuff. Building Jhin for maximum movement speed or damage and just nyooming around. 1-shotting baron with jhin traps in urf while both teams stood around emoting. The time me and a sion just stood there dancing in lane for the whole game instead of hitting each other. Playing AP Lucian mid as a challenge from a friend and going 7/1. Custom games where everyone had to use the same rune and mythic. I reached platinum, I did the ranked grind, but the fun was always in the silly and the community.
