OH man, I tried 3 months ago and I was fine in BW playing Hunters and BGH 2v2, and then I loaded a custom map...
ZERO CLUTTER... no rush 20.. lol. I had a fleet of carriers and the game lasted 2.5 hours, and it was just a game where each side had max carriers/dragoons. I finally punched through with a nice arbiter recall that screwed the economy over of the other side. Sooner or later their defenses crumbled,... gosh my stomach was aching by the time I finished... totally messed my eating schedule up.
