[Sombre]

Yeah I'll bost their stealth. Scouts have 10 now do they? Or 5?

I think I might boost the Augur upkeep even more, though not by much. I like the fact that getting a crummy one is even more painful.

Regarding the blackwing and companions, I do see what you mean. The blackwing are very fragile indeed and tend to get shredded by almost anything they fight, despite good stats. I think it's reasonable for me to improve their armour in some way. They also have the disadvantage of not having a recruitable flying commander, though that isn't particularly hard for Arga to rectify with summons or items. They're a niche unit for sure.

Sworn Companions are a different story. The reason their cost is so high is that they've been price-hiked several times. At their old price I'm pretty sure they were overpowered. The problem is they can do a huge amount of damage in very short order on the charge and more importantly, they have fear. This means if you get enough of them they can simply ride through huge armies, routing them after a turn or two of melee and killing a huge number as they try to run away. Now it's hard to mass Companions, that's for sure, but if you get around 10 of them they really can be nuts.
