Summoner's Rift Variations
I think there should be variations of Summoner's Rift to make gameplay more new, unique, and fun for old players and new players alike. Certain variations that tie back into lore, like a Shurima (Desert) themed map, Demacian vs Noxus (Half-Demacia, Half-Noxus), Ionian (Japanese-styled kinda.), Zaun (Industrial, etc), and of course the regular rift. Keep in mind that the environment effects wouldn't change, but it would just change how it looked.
