What is the Real problem with war thunder?

many people would agree that the one of the worst thing that can happen to you in war thunder is getting kill by a veh that are overpowered in their BR… and most of them are premium locked behind giving money to gaijin.
one of the example of that is T58 tank, in that BR range from 7.7 to 9.7 there is honestly no fun for other nation such as sweden and germany you are getting shell after shell by t58 players who have money or are willing to spend the money on the game. A game should be fun not a suffering that its fun are locked behind giving money and buying overpowered stuff. for example one of the fun of the games is too get a nuke in GRB but from 7.7 to 9.7 most of the nuke of the games is getting dropped by the T58 the game needs a rework on the balancing system so that everybody can enjoy the game not buying the enjoyment from the game. I would like to know your idea how gaijin can fix the game not a new game mode but how to make the game enjoyble for everyone on every BR and rank
