I have only one suggestion. One that would fit Dom perfectly: Kalevala.

Instead of all the fantasy stuff mostly suggested here, I'd like to see races based on real folklore. Warhammer, as nice as it is as a boardgame doesn't really belong to Dom. Dom is all about spiced up folklore. Not that I wouldn't mind having some Dino-riding C'tis. Would be fun, but where goes the line between WH,Dom and other fantasy titles?

IMHO, Dom should stay in the course it has so far been on.
I'd really like to see all the WH suff in Dom, but as a mod. I wouldn't cry if there was a MiddleEarth mod either.

I like the battle engine of Dom very much. It could be used for "historical" simulation too. Some historical races, Assyrians, Babylonians, Late Kingdom Egyptians. No magic (maybe some weak rituals), just priests. Of course this would require all magic to be turned off in the server or they would be beaten to pulp. Anyway a real world setting would be a nice option...

Also a new magic path to go with the Kalevala-race.
Chanting. It couldn't be piled and stored as magic gems or bloodslaves. It would be dependent of the amount of singing and chanting created by characters present at the battle or in a province. Works a bit like the master-slave spells in Dom2. The one doing a Chant ritual would draw on the power of the chanting in the same province or battle.

I think Chanting should be included in Dom even if the Kalevala race would not. Chanting and singing is throghout time the most common way of doing magic for most cultures.
It's STILL done in all the so called modern cultures. Just go to the closest church/temple you find and listen a bit.
