Have you ever thought about creating gloves with the power to alter the attack type of punches? For example, flaming gauntlets will attack on fire, icy gloves attack on freezing bite.. I have never played a serious h2h character but it would give them more options. Perhaps even have a choice (once you choose h2h as a spec) as to which focus (ie elemental attack) you want to go and allow the warrior to toggle it off and on.
