agreed bucky. Some people are just born with a lower capability than others. Not bad, some of them are among my best friends, but they just can't do some things as good.
And the converse is true: Some people are born with greater natural ability. In AH, some are better pilots than others, and some are better GV'ers than others. You can make up for it by studying ACM, or learning what makes good cover and where the soft spots on certian tanks are, but thats not going to completely make up for a lack of skill.
