I am actually wondering if Sword Units actually have an advantage over Spear Units, or are these equally treated as Inf vs Inf in Rome II?

I started a Campaign with Epirus after having played with Rome, and they have no Sword Units at all, will that be a disadvantage?

I like the distinction between Hoplite Phalanx and Pike Phalanx too in the game.

However, neither seems to be holding Formation if Ordered to Attack...(I am hoping this is something that will be fixed down the line)...

And finally is there a difference between Thureos Spears and Thureos Hoplites?

Stat wise it seems like Thureos Spears have very high Defense capabilities.
