Two questions about cavalry weapons and infantry swords

[Brave Brave Sir Robin]

Well, Celtic swords of the period sometimes had a rounded tip, so they couldn't be used to stab. Otherwise, you are right. A stabbing wound to the abdomen or chest is deadly, but these areas would have been protected by a shield at least. On the other hand, the sheer momentum of a longsword could be used to shatter shields, if not bones. And you don't need to kill your oponent to take him out of the fight.

I think this is represented somewhat by the models in EB. The Neitos and elite Celtic units have sharp tipped longswords to represent the better craftsmanship of their weapons while the Botroas/Bataroas have more rounded blades as their swords were not as well made.

Lance-armed cavalry are useless in melee, because the lance has a long preparation time. Pit two equal units against each other, and have one switch to swords in melee, and you'll see them butcher the lance-armed unit. You can even see it in the animations, the lance doesn't strike as often as the sword. Or spear for that matter.

I respectfully disagree. Lots of tests have been done that have shown that the secondaries are inferior to the lances, slow animations and all. The high lethality more than makes up for it.
