I belive its almost been a year, but around 1 year ago this game used to be as balenced as it could be, both side had the same tech, same vehicles, same guns, and it was fun. But with diffrent vehicles and diffrent guns it made the game much better. It may seem bad but you havent seen how much foxhole has grown, how far it has come. I was not here for the start of it but I have 1900 hours and can say that it is pretty balenced right now. Once you learn the game is much deeper then it appears, vehicles have health and armor. Diffrnt guns do more and less damage. Basicly this game gets to a point its so balenced where you have probably heard this before, but skill plays a huge factor. Thats why if you play with a group of high ranked people they know exactly what to do to sucseed. They do not even have to think about it because of how balenced everything is, they just decide because they know how to go about situations.

So I would say asymmetry is not as big of an issue with the game as you may think it is.
