Assets being repurposed or recolored is a staple of any game development, heck Final Fantasy since the first one re-used assets and just recolored them. There was always like 6 of a monster type that just had a hue change, so this doesn't exactly bother me. Also most mobs aren't alive enough for me to care how they look mainly. But armour makes sense that they shouldn't of cut corners as much as they did.
