Hypaspistai

[Timoleon]

I started using Hypaspistai in my Makedonian campaign and I noticed that they have swords as their primary weapon and spears as their secondary. Why is that? It makes them a bit awkward to use. How do you use such a peculiar combination? Which files do I have to change in order to make spears primary and swords secondary?

Another question is for the historians in this forum. How did Hypaspistai evolve after Alexander the Great? Did they just joined the phalanx? Did they retain their distinct role in the battlefield? If I'm not mistaken, they aren't mentioned in the battles against the Romans in the 2nd century BC.
