Listen guys, if you want to have fun, do not play this game. It is a horrendous husk of a game and could not be enjoyed by even the most prolific players.

Gaijin Entertainment (the developer) blatantly uses money grabbing, pay to win methods to entice their players from taking their either hard earned, cold, hard cash, or their 600lb Mom's wallet to buy their way into the higher tiers and to have an edge against their players who have done the same, or are playing the game proper and grinding to get into the higher tiers like you should. They also use this method for you to buy their premium service, in order to allow you to make more Silver Lions. Steer clear of the game, go play DCS, Gunner, Heat, PC, or IL2 Sturmovik.
