Well tonight I was enjoying another round of editing the Edu before tommorrow's patch and noticed that all the pike-spear units were missing the "mount_effect" listed in the older Edu of RTW.
I wondered if this could have possible explained the weak performance of a phalanx pike formation versus a headon charge from cavalry ( besides the fact cav charges are overpowered at the moment in game).
So I added the "mount_effect" "horse +10" under the "soldier" line in the EDU to many different spear and pike units from the same comparable era ( early vs early, late vs late etc). During the custom battles I did see quite the improvement vs cavalry head-on charges with full phalanx or shield-wall formation.
Iam not sure if the "mount_effect" also effects the secondary weapon ( blades) perhaps an experienced Total war modder here could let us know?
