Custom maps in arena

Hi guys. Today I’ve been playing some good custom games with some friends on some well made custom maps, and I’ve been wondering, why isn’t there a mode in social arena that focuses on custom maps only? I’m aware of the occasional modes that do feature maps, but don’t you wish there was a permanent mode that is updated frequently with new maps from the community? These maps can vary on modes like strongholds etc. Or maybe even a permanent community doubles for you 2 man teams out there?
Let me know what you guys think. Maybe if enough of you agree, they’ll make it happen.
