I had included several very simple 2v2 maps ie forbidden pass, open palms, 5x5 maps in the first pool. I had received quite a lot of complaints about it, so I increased the complexity of maps until I started seeing the opposite side complain.
In any case, quantity of players doesn’t really impact anything for me. Badlands is an 8 player map but it’s literally astro-tier beyond 2v2 with a strictly dominate strategy and even an autolose condition if you get bad random faction luck and roll several Cybran.
But it’s decent for 1v1 and 2v2, regardless of what the map author thought he was making.
Don’t see the problem with Wonder. It’s possible to delay the enemy expansion but actually taking it over is extremely hard due to the fact reinforcement is much harder from the side attacking and the side defending has a wide open plain that can put 2x eco into helping secure that side.
Also another point:
Adaptive Monument Valley is a 12 player map
but Adaptive maps adjust mexes based on player count, so the player count of the map is irrelevant and rather the competency of author mex placement is what matters.
