I think that this is a bit silly because I love playing as a tank commander. I do very well in a round, and no stat unlocks or class progress. I think that this is a bit disappointing because I do some great work for the team in my tank, but at the end of the day nothing ranks up except the MG-34. There should at least be something like your loader is able to load faster, or unlocks like a rammer or gun laying drive or something like that.
