Unrealized potential of tiles?

So after firing up OP4 I noticed we got a new hord exclusive map, it might just be tiles, but i enjoyed it a lot. I know they have already shifted resources away from tiles to work on more maps, but this got me thinking we could have a larger library of hord and pvp maps if they just utilized the tiles they already have.

We have yet to get a free for all map with the barracks tile set. Or any 2v2 maps with them. I know TC test their maps like crazy, but do we really need a ton of testing for hord maps? Leave it up to the community to decide if its a bust or not.
