I've always been bothered by how faint the White Hand is on the shields of the Uruk-Hai. I suggest that it should be made a brighter white, like what's on the berserker helmet. That way it would be more visiible on the battlefield as well as just looking better. Another small change could be (if not too difficult to code) that Dunlendings could uncommonly carry the shield of the White Hand as well, as a symbol of their loyalty to Saruman.
