It'd be nice if pikemen had some defensive capability against mounted troops and beasts as well as their special attacks - say a bonus to defence against cavalry unless getting attacked from behind, being immune to the mounted 'Flanking' special attack, and to 'Mounted Charge' (again). I know it's a fantasy game, but this would make them seem more like real medieval pikemen actually were and make it seem more authentic. It'd also make them a more useful unit. Currently they just become obsolete later in the game.
