Even though this went off topic, ultimately this conclusion leads us back to what is at hand.
No one claimed that the game is totally balanced or that you shouldn't doubt the balance team. The point that was made was only that you need to be careful drawing conclusions from these stats, because they likely do not paint a complete picture. The non top 200 stats are likely more heavily influenced by some external factors such as map pool and (lack of) player skill, while top 200 stats with 200-400 games are too small a sample size to be reliable and obviously vary too wildly (60/40 wr in 3v3 vs 40/60 wr in 4v4) to be anything close to conclusive. Which really is a shame because as they'd likely be the best representation of balance.
Are Axis a bit too powerful in teamgames at the moment? I'd say probably yes.
Is it as bad as these raw stats seem to suggest? I don't think so.

And people, as usual, do not consider the map pool when analyzing balance. Each map pool will have an effect on balance in a significant way.
