Ugly armours and too much armour: Most of the armours look ok to me, some I really like, but I dislike the bulkiness of some troops and over abundance of metal even on mid tier troops. If Calradia at this time broadly reflects dark ages and a bit later, then I would like to see fewer troops with metal armours (though I hate leather and studded stuff; just give them normal clothes, maybe some with furs, and have majority cope with shield and helmet for protection) and fewer barded horses. That's not to say the horse bards don't generally look nice, they do, but I feel a bit like they shouldn't be so prevalent; each faction seems to have them for their high tier cav. It's especially strange to see such horses getting so easily hacked down. I could be wrong about my impression that there wouldn't be so many well armoured troops in this era. On further thought I may also be getting a skewed impression of the number of armoured troops by the Captain Mode vids, when I suppose the troops might not be quite the same as in the main game.
The ugly armours though are ones such as the Battanian axemen one with the chunky small breastplate; he already wears a scale vest (with mail visible on the upper arms), but apparently needs this small and overly decorated breastplate which is secured by a harness with chunky leather and metal shoulder pads. I don't like the colour of the metal on this troop either, it makes it look rather flat (I think it's a realistic finish to the metal, I've seen metal weapons and armour like that, but I just don't find it appealing). I think it is a sort of matte polish. In contrast most of the scale armours of the Empire look gorgeous.
