Pay to win and unbalanced game play. Grinding is almost impossible 6 thru 8 of the 10 tiers as to many premium tanks make for a longer then necessary grind. Lights tanks take out heavy's and TD's with ease. Be prepared to rage quit many times as the game seems to be riddled with cheats allowing shots thru walls, auto aiming and damaging modules are common cheats employed. All this of course is denied by the publisher.
But game has cool graphics...
