I used to play WoWs in Steam/Proton using my old account and it worked fine until today as WG removed the possibility to use old accounts in Steam even with a workaround.
I tried wine via Lutris and managed to install the horrible and useless Wargaming Center. I was able to install WoWs too, but it crashes right on start.
It was working fine until yesterday. I don't know why they invest so much time and resources to make players leave the game.
