Couldn't agree more.
There is a way to have Morghasts be -3 rend (already -2, a further -1 from Bludgeon), +1 to hit (helm of the ordained?), reroll 1's to hit (soulguide) can't remember) and +1 attack(Endless Duty). But it involves keeping 2 characters relatively near them. I just love the models too much I suppose
