I quit WT around 2019 or thereabouts. A certain amount of grinding is OK, but an economy xhange made it impossible to play the vehicles I already owned without grinding in between to afford the repair cost.
It happend around june this year. Grind and economy was really bad. People were mad, Gaijin didnt listen and one day they made some PR faux pas, which resulted in review bombing and boycott. And since then... Gaijin actually listened and they fixed the game. Economy is much better, you can even have a bad game on br 8.0 and still have positive income. And amount of exp needed to grind to the top vehicles got halved
