You answered your own question. Natural physics makes the forehand the more dangerous and powerful stroke, as well as the harder to develop. A player with a great forehand is always dangerous even if the backhand is shit; if your backhand is great but your forehand is shit, you'll never be enough of a threat to make it as a pro player...
