Some questions about the units.

[Akka]

I've had for a long time wondered about the stat of some units in the game, and in the end I come and ask the pro to have an answer.

The culprits are basic units : town militia, spear militia and byzantine spearmen.

Basically, these three units have the same stat. I've never really understood what was the difference between town militia and spear militia. The latter cost 20 more to create, but except that, I didn't see any difference. Can someone enlighten me ?

The Byzantine Spearmen is even more confusing. The description say that they're a step up from other militia. Ok, so I looked into the files.
Same attack, same defense, same moral, same discipline.
For now, the only differences I could see are :
- They cost nearly a quarter more in upkeep.
- Their armour can only be upgraded twice and not thrice.
- They are not a "free upkeep" unit.

So in other words... they are considered a step-up, they are more expensive, and compared to standard spear militia is that they have no advantage and are less upgradable ?

You can guess I'm a bit at a loss here.

Sooo... anyone knows about something I may have missed ? ^^
