I agree wit this sentiment. The new Ancient Undead faction looks great (and also incredibly, incredibly, hard to fight). The generic and newer undead were challenging and pretty cool. I replayed my one battle against them three times and didn’t win. It would be good to have an undisciplined, shambling undead in the game as a stepping stone, maybe they could just be linked to graveyards and fortresses. The way they were spread out was evocative of newly risen skeletons, still somewhat purposeless – until the player comes into their ken.
All the best
