I think Xu Huang is an underrated fighter for Wei, not very involved in many storylines but is a fierce warrior and his weapon is one of the most unique but generic of them all. A simple battle axe seems generic but the additions its received and the fact that no one else carries one makes the weapon a stand-alone in the series. Love using him in DW4 and again at times in DW5 but kind of drifted from him in future installments due to the amount of characters increasing while Xu Huang never seems to improve in his speed, moveset, etc.
