I do agree from my 3v3 experience, but I still need some L2P .
Fact is there is a quite big difference between:
a) different modes (1v1, 2v2, 3v3 and 4v4). For instance, Axis is quite powerfull in 2v2s.
b) arranged teams and randoms (and these categories are mixed quite alot in automathces unfortunately).
Just experience from grabbing the top 1 Allies of 3v3 within few hours, I defined that as easy, cheesey, and overpowered.
