Armor and weapons smithy upgrades???

[Bassilisk]

One of the games I have loved the most in this genre is Medieval Total War the first one....if only it had multiplayer campaigns....Anyway the game had options to upgrade weapons and armor which would give you bonuses in combat. I liked this idea as it gave depth so that each troup/army was able to have or not have multiple upgrades. Would be cool to see this mechanic add layers to battles, both auto-resolve and ones you personally command

From what we saw so far there is no such thing in KoH2. It appears that you are locked into unit types such that your upgrade path is to add a new building which has stronger unit types available. But units of a same unit type are identical apart from veterancy levels and religion/kingdom advantages bonuses plus marshal skills on top of that.
