New game type/map idea!

This map is a one on one maze-style map with a lot of open area. You and an opponent try to get your minions to the enemy nexus to destroy it, and you can't target turrets, inhibitors, etc. This map is a tower defense map, and while you can play any champion, various items are exclusive to the map: heimerdinger-style turrets. You buy turrets and place them down in a path in an effort to try and stop the enemy minions to getting to your base, seeing as if you don't build anything they can walk straight to it and win the game. You can still target the minions and the enemy champion, but that won't be the best way to go about defending your base.
