I have always felt strange about Devs give spearman from different civs with same European guisarme.
Or they might believe that universal guisarme can increase the recognition of spearman’s level.
So, just as my title saying, since you give the spearman with a fire lance, in order to let your opponent know that you have select the option named Roar of the Dragon, you should let ZXL’s spearman hold that fire lance when idling but not only when charging.
This is also for the sake of recognition and competition.
