World of Tanks is a selfish game. It acts selfishly in that it hides information from its players, expecting them to figure out any and all intricacies on their own. Similarly, it asks its userbase to roll into combat as a team, but only concern themselves with individual performance. Selfishness permeates the spirit of this game.
Though, I suppose we shouldn't expect any different from World of Tanks. Simple as the premise may be, real tank conflict would be undoubtedly difficult, and these types of titles tend to skew toward realistic to a degree. All's fair in love and war(gaming).
