Since very little has changed since my post in the beta board I'm going to paste most of what I said about this class in there:
I'm still not a fan of the cost reduction this and many other classes got in one of the late beta patches, this class, along with the sergeant, the oathsworn and the varyag used to cost 150g and I think it should go back to that value.
I think the spatha (default sword) is overall a decent weapon, it has good speed and damage values but might be a bit too short when compared with similar weapons, making it slightly longer or replacing it with the long spatha might be worth considering.
As for the perks, the perk mace is pretty slow and its length also makes it a bit unreliable when up close, but it still can come in useful in certain situations. The shield perk is just worthless, while the default one is on the heavier side when it comes to infantry shields and slows down a class that is already slower than similar units, it is a pretty reliable shield, this perk offers little difference in terms of protection and simply can't compete with the improved armor option.
In the second row of perks, the spear and the pila are fine, but the axe is a bit problematic: while it is by far the best one-handed axe in the game, it also leaves you with two melee weapons and just doesn't offer the utility the other perks do. In my opinion this perk should be moved to the first row so that it competes with the mace and the improved armor, it should be a solid pick when axes inevitably become stronger in the future.
The way the pila perk works has changed a bit since the beta, it now occupies two item slots and is on melee mode by default, I honestly can't see the reasoning behind this change and think that it should be changed back to how it worked in the beta (throwing mode by default and both pila sharing a quiver occupying only 1 slot).
Also in my opinion the helmet should change when choosing the improved armor perk.
I think that legionaries should be more expensive, they are easily the best all around infantry class. The fact that you can double spawn first round as legionary is why Empire wins so often.
I don't see how this class is overall any better than the sergeant or the varyag, in that regard I'd say it's in a fairly balanced spot.
I think it’s balanced to let them be strong in infantry combat but don’t let them get spears to counter cav. That being said I think a 10g increase is fair.
That's really not a good idea, removing this class' access to spears would pretty much ruin it and very likely doom the whole faction in terms of balance since the other anti-cav alternatives available (recruit with spear and menavlion infantry) are very vulnerable to ranged attacks and thus, unreliable.
