Hi, and thank you so much for all of this info! Would you recommend the Mantic ID army manticgames.com/games/new/abyssal-dwarf-army-2020/ as a good starting point? Thanks again!
i say go for it!
for EW starter armies we have 1 characters and 3 units. so the Mantic set (with Overmaster, Halfbreeds, Blacksouls and Decimators) can probably cover almost everything you need.
in Essence of War, just like in The Ninth Age, all that matters is that (1) your units are on the right base and (2) they can be clearly distinguished. so even if the new EW patrol for ID will have different specific units, you can still represent them well enough with the Mantic set.
you might end up having half a dozen unused model (and maybe needing a couple more models), but with the battalion you linked you'll cover some 95% of the army. and with that im gonna shut my spoiling mouth : )
