All comes down how good is your team or enemy team.
I have been in plenty matches where enemy team totally obliterated us on every point. They knew how to work as team while my team was all the fucking time fighting at same point for no good reason instead of spreading around map trying to take points.
Also depends on map. As tank driver in map like Berlin (Awesome map btw) is pain to fight on the tight streets.
As very good tank driver I could not do shit against those teams, my tank was instantly killed, bombarded from all sides.
When all 3 visual systems of a tank are destroyed, tank driver can not see shit, and it is pain in the neck to get your tank to the home base for repairs. This should be fixed so that you can at least get to the home base.
Anti tank mines are OP, killing a tank with 1 mine is to easy, killing a tank with 2 or 3 mines should be fine. Soon as a tank driver I will not be able to drive around because there will be mines on every base and every choke points.
Tanks prices are fine. Maybe they should reduce artillery cost or increase artillery spread and damage.
