I don't even have an Asia Server account.
I have my NA account still which I stopped playing for over a year, and only during Xmas re-investigated for about 5 days maybe, and was immediately turned off by the losing Match Maker, the Maps, questionable RNG, the new equipment changes ( which were new to me, because it occurred during the summer, because I was not playing ), and other things etc.
Wargaming always is doing shitty things like this to everyone on the different servers. They pull these scams every single time at various intervals making someone else wealthy locally, and enriching themselves at the top. Which explains why these so call mistakes, or "incidents" seem to occur on a regular basis. They are explained as slight oversights each time; however, they seldom are.
There's no oversight on these matters at all. No one safe guarding to make sure the player base is being protected from these deliberate shenanigans and improprieties that take place. Wargaming always get's away with these capers every time. And, a frustrated player base, either leaves, or learns to "suck it up." Nothing ever truly changes at that level at Wargaming.
On some occasions, I remember some nights I played on the NA server at it's height the population would hit as high as 52K, for a 2 hr. period on a Friday night. But, quickly being call a liar, a deceiver, a fabricator, by the NA Wargaming company trolls, WG NA itself even notated an number higher than that as an "all time high for the NA, and posted it the NA Forum." lt was quickly Removed by their office trolls, after it had been posted on their forum by the players themselves.
When it come's to Wargaming, you're not dealing with a honest, transparent, legitimate, company in any way.
None of what you have posted come's as any shock to us, "What so ever!"
