The game is great but overgindy, I'm currently main on 2 country (China and Soviet) and both of them are at 5.7 both Air and ground. I prefer to play on 2.0-4.0 match since it's where armor still exist and on 5.7 Ebr are dominating. This game is fun if you play as tank game this is not a game for player who want fast progression since on 500+ hours i only got 5.7 on both country (I used to play arcade a lot 2/3 are arcade and now mainly realistic ever since i got open top vehicles) (Btw on realistic you get more research points)
I saw a lot complain about the ghost shell problem, as a 500+ hours player the ghost shell only happens if you got ping drop, last month i got a whole month wifi problem, that is where ghost shell and packet loss first happened for me. (That what i believe)
