why does this game have a steep learning curve?

eekeeboo: It's also important to remember that as the game has aged and evolved, the amount of information and things to learn has increased dramatically also. In the old days of 2 nations with few tank lines, it wasn't that much of an issue.    No amount of tutorial (if people actually go through them) can help you learn all the match-ups, map positions and other things you learn as you play.
