We know that the Jin Empire's hired martial arts mercenaries from LOCH (i.e. Au Yeung Hak, Ling Tze Seung Yan, Leung Tze Yung, Sa Tung Teen, Pang Lin Fu, etc.) were, as a group and individually, weaker than the Mongol Empire's equivalent crew of mercenaries in ROCH (i.e. Fok Do, Dat Yee Ba, Wan Hak Sai, Siu Seung Tze, Lui Mor Singh). How great was the discrepancy between their levels, though? Was Fok Do's martial arts twice as good as Au Yeung Hak's ever were? Was Dat Yee Ba as powerful as two Ling Tze Seung Yans? Could Siu Seung Tze take on two Sa Tung Teens?
Moreover, if the Golden Wheel Monk had to fight Gwok Jing during ROCH with the help of the Jin flunkies instead of with Wan, Siu, and Lui, would the Jin mercs be able to help the Golden Wheel Monk at all, or would be they be too weak to contribute anything of importance?
