This is just an idea so if any map makers wants to make this into an actual map please let me know and give me some credit for it. It is a 1v1 or 2v2 map that is 1 lane that is a big U.
The hellborne and legion sides are divided by a big pool of lava in the middle, big enough that heroes with blinks like mage bane or valks jump cant get over and if they do jump into the lava their health is drained very rapidly (it would inflict true damage so there wouldnt be anyway to glitch over the pool). There would be the main base then it would go out and there would be 2 towers, 1 on each side of the lane. it then goes all the way up to the middle of the U where there are 2 towers for the legion and hellborne teams.
This is where it gets interesting. Since there are 2 hellborne and 2 legion towers in the middle it makes it difficult for the player(s) to kill the towers. This area would also be a main battle area since it is the center of the map. Also for ganks there would be jungles on each side of the lane with neutrals inside for farming. Also at the middle there will be a path leading off to a Kongore spawnpoint.
