Got and upgraded the most expensive tank you can buy without using money in 2 days (<4 hours). As the top 3 can only be bought with real life currency or by gambling with the "premium spins" (I am sure the devs pay gambling tax right?)

Power ups (except repair maybe) are useless and overpriced. The airstrike drops a puny grenade that does not kill your enemy.
The flamethrower has no use as staying at the border of render distance makes enemies docile.
(Which is how I completed veteran mission with starter tank). 

The bomb supply trucks are parked in a river because f physics. So I simply drove off the bridge since there is no fall damage and you land right side up. Who needs to kill enemies when you can simply do the objective?

You might as well drive backwards because getting hit in the front armor does the same amount of damage as getting hit in the engine. Not to mention deflecting shells is a myth.

Once you completed the veteran mission watch a 30 sec add to DOUBLE the rewards. Ez money.

After you get the T-34/85 there is no reason to play anymore as cash and cold bars are useless.

And the devs REALLY think buying the tiger tank is worth 40 euro's with the state of the game? Pathetic
