Picked up the game and been playing the last few days. My biggest griped is that the buildings are extremely hard to distinguish visually.
I cannot tell what the opponent has built in their base with a fly by scout, or what kind of resource is in front of me, or if an extractor is build on the node without clicking each individual one or zooming in extremely close. Everything just looks like a blocky pattern. I can usually tell, "Well, that's a turret I guess because fire is coming out of it.", but only when close by.
