I dont know how things will turn out when I fight real enemies, but so far Repanse vs undead on small unit size does have a bit of that Dark Omen feel. The only issue is compared to Dark Omen, my missile units are complete trash so I have to rely on the old hammer and anvil all the time.
Also yeah Repanse and Henry are kind of busted, I wonder if I should have a full paladin stack going into lategame.
