This would however still make elemental attacks and defenses useless. If for example my air character got 4 earth attack to attack an earth charater who had 4 water defense, the other player, seeing that my character has earth attack, could sell his water resistance and buy air resistance. Then I could sell my earth attack and buy fire attack to attack his fire character, and then he would sell his earth characters air resistance and give it to his fire character, or just transfer the enchanted item to his fire character and etc. and in the end the battle would be decided by who logged on and modyfied his characaters last. And all this attack and defense type changing would cost at most 50 gold to each player.
