I agree this would help solve a lot of problems, but sadly this is something that has been brought up many times. A lot of people have given detailed feedback on why the GC Restriction is a problem for us, and how those problems could be solved... but as things stand:
- They have not acknowledged that the long, unpredictable, and inconsistent wait times we get, when the possibility of nearly instant and continuous gameplay exists, is a problem to them.
- They have not acknowledged the very unequal player experience that comes from having a mostly static pool from which allies and opponents can be drawn.

Personally, I've expended about all the effort I plan to on providing input re: how they can make things better, and why they should, because not one thing has been said to indicate the feedback has been valued or will be given additional consideration.
