New Regional unit proposal: mounted crossbowman

Mounted xbowmen were deployed together with lancers+ light cavalry to charge at enemy heavy cavalry and pikes. Mounted Crossbowmen discharged a bolt before enemy lancers successfully attack friendly lancers. Friendly lancers can have number advantage to fight enemy lancers. The enemy lancers had ways to fight back actually. The lancers can pursue mounted crossbowman.

Mounted Crossbowmen could also open a gap in pike formation before lancer charge.

So it can have bonus damage vs pikes and cavalry. But we have mameluke with bonus damage vs cavalry in the game. Heavy cavalry can actually fight back mounted crossbowmen while pikemen cannot. So I choose anti-spear bonus for them.

This is true. But Chinese mounted crossbowmen seemed to be a bit different. What I find is only against Xiongnu and Khitan heavy cavalry. But no evidence against pikes yet. I still need more time to research Chinese mounted crossbowmen.
