The devs hold you in contempt, the only reason this game is still active is there is no other game similar. As of now (and it has been for a long time) you need to pay for premium time and have a premium vehicle to make any progress or earn silvers. The devs consistently nerf game-modes with obscene costs so any in game currency earned is mostly eaten by repairs.
There are cheating problems in all modes but there's no report system that does anything. Expect to get one shot through walls and impossibly small holes in the tank mode, air to air missles that won't miss and planes that magically take no damage in the air modes.
This game lures you in and then proceeds to farm you for as much money as it can manage. It's not uncommon to get your lineup completely wiped without earning enough points to not lose currency. This game will end up in the same state as the wargaming titles currently are.
