WHY DOES LEAGUE NOT HAVE A 3D GAME MODE YET?!

Think to yourself what game came out with 3D but copied league? Thats right Smite did. Now I believe League can perhaps double there number of players by simply adding a 3D Game Mode. Look at Smite. Smite is Garbage™ but they have such a consistent player base because of there 3D World. Think about it from a console players perspective what games are top down on console? Name more than 5 and I applause you. Adding in a 3D Game Mode would drag in much more different players. It cannot be hard for league to add 3D seeing as the game already takes place in 3D but from a top down view. All Riot would need to do is change the camera. If League were to add 3D it would change the way you play ENTIRELY but, remember THIS IS A GAME MODE!! Not a ranked game, not an game camera a new game mode.
