This is true in every game since chess. When advancing a pawn, you can choose what ever piece you would like to promote it to, but it's never to your advantage to promote it to rook rather than a queen. I guess that makes chess a horrible game, filled with flaws. Take what ever skills you want... and if you think some are wasted, simply ignore them. Others play by different rulesets... perhaps trying to end the game with the most gold... who knows?
