This would absolutely ruin ground rb.
Put low-levels rank 6+ in a separate queue from everyone else, and remove all rank 6+ premiums.
That would never work, for the reasons I stated above. Although if you coupled that with BR decompression, and then packed low and mid tier only with premiums, while then only allowing the last two tiers to be grind-only, that would be feasible as a business model.
However, that would be a major game overhaul and Gaijin would have to have a reasonable cost-benefit analysis that would justify investing that many man-hours (money). In other words, a company is not going to spend money to overhaul their structural business model unless the change both pays for the investment and yields more income, which it would not. So what you are proposing will never happen.
There are PLENTY of rank 6+ premium players to fill queue slots, and not only that, they’d be more likely to stick around since they’re not fighting lvl 100s with thousands of hours.
Your idea would not change the game because if Gajin don’t put premium in rank 6 then Wargaming will fill the gap anyway.
Gaijin cannot force players to spawn twice.
Blaming devs for players poor choices isn’t helpful; neither is blaming the players for that matter.
That’s a good way to end War Thunder. Punishing behavior is not how you provide a healthy game.
i have not seen higher levels really do that as they atleast have some lineups
You don’t play a lot of top tier battles. I see lvl 50-100 in prem Soviet tank T-80U-E1 quit after being kil so they have line up but decide to quit instead to play further.
