Mirror Map Mode
Something like this

The idea is fairly simple, mirror Summoner's rift horizontaly, so instead of both teams spawning from Bottom Left and Top Right, they spawn from Top Left and Bottom Right. Why Horizontally? Because I guess would be easier to mirror assests and textures horizontally than making new ones.
Why mirror map? This is something that in any game with a map you spend a lot of hours in is fun. Because you already have the map memorized and ingrained where everything is, how a wall acts, where you must move, mirroring it can actually make you feel you know nothing.
Is a silly simple idea, but for like April's Fool or something it can be very fun.
What do you think?
