2v2 Comp Maps

Just a question:

Is it a possibility that 2v2C gets updated with more maps mid summer season? I find it quiet lacking in that regards… I mean… There are only what? 5 Maps?

Truth
Regret
Empire
Plaza
The Rig
?

How Maps like Mercy aren’t in there is beyond me… But maybe there’s a Reason why there are only that few, but that reasoning I would like to hear.
