Broken Empire has some interesting strategies, starts with Body Ethereal, they can combine living and undead armies very well, they Reanimate Longdead Legionaires... I'd really like to play them. Unfortunately, they have very weak mages. I'm not sure how or if they are changed for DomIII, but I'm expecting some minor improvements. I'd really like to see them have different sacred units, the current ones are inferior to Body Etherealized Principes.
I think BE Ermor is similar to Ulm in Dom:PPP - while it hasn't changed much, Ulm now has other options through themes, and has gotten several specialized troops that have opened different tactics. But even with Sappers and Siege Engineers, Ulm is weaker in the endgame. Ulm can shine, through very spesific route (Forge of the Ancients, lots of Constructs pumped out by the high-Earth pretender), and I'd like to try Broken Empire with pretender that could really benefit from Enchantment. I'm hoping something along the lines of W5E6 Daughter of the River in Dom3 - the priests will become sacred (
from this post ) and thus they would benefit from reinvigoration, and this would allow early Raise Skeletons, bonus for Claymen, and later bonus for Enlivened Statues.
