Battle BR asymmetry problem

It’s been for a while, but I’m quite frequently joining games with assymetrical BR balance.
For example one team’s BR caps at 6.7 max, while other one having at least one (usually more) of 7.3 (don’t remember anything higher) BR tanks. That’s just plain text UN-FA-IR. And I think should be fixed asap.
What is wrong with this game? Who made this decision? Are those mythical “queue times” influencing game design again? What a bunch of baloney.

in my experience its normally some like level 13 on your team with an 2.3 tank and a helicopter

In air using the f16a-12.3 many times im the only 12.3. Everyone else 12.7+

Its no conspiracy- the game is rigged.

No, I’m telling you, the team BR caps at 6.7, I checked every single player myself every time
