I hopped into this today for the first time since the beta.
I queued up for the solo mode.
It found a whopping 14 people (after waiting for several minutes).
This was the map:
For reference, the entire square is the full map that you'd be playing on if you got a full lobby, but since only like a dozen people were in that match, it restricted us to a handful of buildings
I see why they're giving away coupons to people who play this game.
I just hope that I get my coupon, I hit the "request" button before I booted up the game today and I can't re-request the coupon
