Different Styles of Summoners Rift
If you're like who plays league so much you just ignore all other games on the market, you might get A little tired of seeing summoners rift. I think maybe Rito Game should do something like GTA V did where when it was Christmas they covered the map with snow. This could bring a little freshness to the best MOBA map ever. Maybe they could be sold like skins or they could be changed throughout the irl seasons in small patches, if the player chooses (If they don't want this they can turn it off in settings.)
Summer: Things are brighter, shinier, a little more yellowish to show heat.
Spring: Make things look more wet, make things look like they're growing.
Fall: Brown, bushes are piles of leaves.
Winter: Rivers are iced over, snow everywhere.
