You can literally play this game for years and barley get any progress..I'm a firm believer gaijin will make the game harder for you, gaijin wants the player the community to struggle thus forcing some/most people to pay for progress(example At the beginning of researching the Mig 29. In a good match I would get 7000 research points, now after a few days of quickly grinding up regardless how much I Excel in a match I don't get more then 2000 research point) it's simple gaijin has the ability by it's matchmaking and it's weapons control/nerf to effect your progress,example
one match my missile are hitting every single target couple matches down the line my missiles won't hit properly, that's called progress control gaijin has the ability of controlling your progress
