Screwy mechanics of sword&spear infantry

[Aper]

No, it's not a bug, there's a reason (that I don't remember), but I agree with you: secondary spears are useless, because in melee elites are better than cavalry even using swords, but they got slaughtered easily by whatever good shock cavalry that charge them, and is absolutely frustrating have a spear in your pocket and can't use it for his purpose: defending you against charging horses...
AFAIK, you have to change the EDU, the animations, the skins and the models to have primary spears, and it is beyond my modding skill, so...
1) I switch the model, etc... with another who have spears as primary weapons, but doing so you lose the uniqueness of beautiful units like Hypaspistai or Baktrioi Agema....
2) I use them like swordsmans only, and I protect them with light spearmen like Thureophoroi, that have even some handy javelins...
