Sort:  

tanks are supposed to tank damage from basic Infantry weapons.
tank to tank battles are an entirely different thing...

and by the way, that woulkd be quite ridiculous if they could not hurt each other.

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.
