Do you have a better system in mind? Because just saying “go by hard metrics” is a meaningless platitude. People with thousands of battles disagree all the time about which hard factors are more important. Hell, so do the real world engineers that work on these things.
If you’re referring to vehicles played by a small number of people, they say they do weigh that in. Whether you believe it or not is up to you. However, I feel compelled to point out that they are a business. Their BR decisions are clearly based, not just on how a vehicle is performing in competitive terms, but how much SL/RP per battle it nets a player in relation to its rank. In other words, efficiency.
See what @RunaDacino has already explained.
Lol no. Why would they do this? Their objective is player retention. If you exclude inexperienced players from a vehicle’s statistics, those worse players are going to have a bad time and may even quit the game.
Like, hello? This is an MMO. You structurally cannot play it without other people!
It’s not in their commercial interest to do this. You are raising barriers of entry into different game modes by only balancing BRs on the people who are already good. But people starting a mode afresh are likelier to buy premiums and populate different areas of the MM as they progress through a tree.
You fundamentally misunderstand what the BR system is for.
The BR system is not to sort vehicles into competitive brackets all else being equal, because it is impossible to separate the vehicle from the player - no vehicle in the game plays itself - and more importantly, because Gaijin’s customers aren’t the vehicles.
The players are the customers. All the players, even the bad ones. So Gaijin will try to standardise the experience of all the players. Which is why vehicle statistics include all the players.
This idea of “harmful stats” is hilariously out of touch man.
It is not a way to bypass anything, since you failed to address all the structural reasons and commercial incentives behind the current BR system.
