I see the OPs point but the trade off is our heroes are meaty! Maybe in the next tome we'll get a Gnoblar hero
I'm preliminarily thinking something like this:
Bloodgullet
Battle Regiment: Butcher, 2x Slaughtermasters, 8 Ironguts, 2 Mournfangs
Linebreaker: Frostlord on Stonehorn (with splatter cleaver, general-Nice Drop), then 2 Stonehorn Beastriders.
4 drop list, plenty of spells to cast, plenty of monsters and battlelines and heroes.
The Battle Regiment could also be switched to a Warlord for the extra 'enhancement' which I think is artefacts?
Ogors will be good and strong I think. Ironguts should outperform.
