New MAps for the modes we have!?

I think that league is an awesome game and the maps are fun, but why not add more maps for the game modes we already have? Adding maps could be like a normal 5v5 with a different style map it could be more based on another part of Runeterra like the sands make a normal 5v5 map with a sands feel to it design and look of a new map would be awesome and give players something else to enjoy about 5v5 and we could do It for other game modes to.
