I’m not ashamed to say it, I spend a lot of money on this game. But lets actually get down to the core of your issue.
Wallet warriors will spend money on their nation to expedite their grind, or simply because they like the vehicle on offer that isn’t in the tech tree. Or, in my case, because its a mixture of the two.
I love my USSR lineup of preems, squad vehicles. (I have the T80U, as well as KA50 for another higher tiered BR bracket.) I would, in fact, be a USSR main if the aviation tree wasn’t so shit.
One death leavers, premium wallet warriors. Well friend, I dont one death leave and the reason is simple. I have more tanks at that BR that I have purchased that I can bring out.
Lets look at another popular nations premium selection.

Either a single tank at 10.7, or a single tank at 11.7 with the option of a squad vehicle at 11.7

Much the same for Great Britain. The solution? Call it cringe, but Gaijin needs to add more premiums.
More money for them, more tanks for us guys with disposable income to make competitive lineups with.
And yeah, while I may have spent a lot of money on this game. I’m not too bad at GRB or ARB. Premium players aren’t the problem.
Buying your way to top tier isn’t even the problem, because lets be real. What does low tier teach you. Top tier consists of aiming, pressing a key to insta rangefind, then click. Everything else is map knowledge and positioning.
Map knowledge being irrelevant because low tier and high tier don’t share the same maps most of the time.
