I've noticed that some units have lost certain abilities, such rapid reload for slingers, or sword band loosing the shield wall and frenzy ability (not sure if that's what it is called but you can view it here right next to shield wallSpoiler Alert, click show to read:
Also spear men seem to have lost the ability to anti cavalry tactics.
Was this removed cause of balance issues? Or will it come later on with more advanced techs and units / more developed generals.
Thanks!
