My friend ran the Cursed Company in his Woodie army at the last LAGT and he found it just didn't make it's points back.
The leader of the unit is strong. No doubt. He stood up to my Lahmian Countess for three rounds of combat once.
However, like any unit of undead it needs to be largish to be effective and it get to be very expensive for what it is.
I think the flages are a great choice and stay within the theme of an empire army much better.
Personnally, while I know that "comp" has been replaced with "theme", DOW units are usually frowned upon by opponents unless you have REALLY figured out a way to make them fit your army.
A big block of undead in the middle of an Empire battle line is gonna stick out like a sore thumb, and I don't think they will really get you much more than the flages.
Except that little "autobreak thing".
Hope you don't run into my army with that unit. I play VC and I would rather see the cursed company then the flages any day.
