They can hurt each other or move or whatever but what happens? Team a camp at respawn, team b camp at respawn. I expected action from the game about tanks.

Can you tell my why do you enjoy this game?

I would suggest you get a fast tank and use it cautiously.
But if you don't like reconnaisance this will not work for you either...
If you play like i do, you will find this game to be very hectic.
