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.
But then every tournament statistics would be invalid as they have an inherent low sample size. There is a difference between sample sizes and trends. Sure, the sizes are not great, but the trend is there, no matter the size. Month after month the axis have 5%+ win advantage which is huge. The only acceptable difference would be 50 +/- 2%. So [48,52]%. And the constant BS about the "pick only top 200" games for the analysis. I've seen sh** players in top 20 that spammed mortar pits and complained how axis is OP when they went down to lefh or stuka or werfer.
Rank means sh**. It's more of a general guideline than an actual rule. If I've managed to go from rank 20 to 300 and back to 50 in a span of 3 days, then you know that the rankings in complete random teams are BS at best. Complete and utter garbage on average.
While I do agree that the stats paint a worse picture than it is, you're not really doing anything to fix the balance problem for 3v3+ modes. A couple of gimmicky buffs for brits and USF (Pesrhing), coupled with hard nerfs (calliope late game arty tank that can only take one shot, while being slow AF) really make me wonder the sanity of your team.
I mean, would you call the following a HUGE BUFF?
Every unit in the brit arsenal, both stock and doctrinal is getting a 1% buff in one area.
On paper, you'd be able to say "we've buffed every unit and brits should now be OP", whereas in reality you've done nothing.
But I don't really blame your team for it. It takes a lot of brain processing power to do a complete overhaul and unless you're getting payed for this, I too wouldn't really be bothered to do a good job. Couple that with the absolute garbage map design in 3v3+ map pool, it's no wonder that the axis has win rate larger than f****ng 5%.
That and your inability to give any sort of late game power to USF that does not crutch on 2x jackson to keep the KTs and tigers in check (well, until the Jagd/ele arrives and the axis just does a hail Mary push with 3+ heavy tanks and elite infantry supported by stukas and werfers and you straight up lose unless you have doctrinal mines on USF). I mean, you don't even have to take the winrates here. There was a post in Trending on the front page, that showed the number of games each faction played in each game mode, both random and AT. Brits and USF were dead last in each mode except 1v1 for USF (which is expected as 1v1 is a completely different balance problem, and USF is the best faction probably for 1v1). Or just sum up the number from the current winrate page.
I'd say that's the biggest proof. The player's unwillingness to play USF/brits in teamgames is there for a reason.
