Thank you for the good work! Though I have to disagree on some issues, as usual.
(What I agree with is the 2 nations idea, though on different basis: I think that in gods-based games, such as Dominions is, it would be simply wrong to include followers of Sigmar and Ulric as one faction. I would prefer that it would be possible to make choice on the Pretender creation stage, but it's not so, alas.
Kislevites I would (and shall) try to make an independent nation.)
0. I still think that Warhammer nations should be LA.
1. Why don't you include firearms as they are? They are surely part of WarHammer world, and balancing them shouldn't be too difficult...
2. I would (and shall, for my version) make a rapier as a new weapon - in any case, it needs to be done when Tilea will be under work... Otherwise, Imperial Swordsmen/Free Companies are often depicted using falchions...
3. I would include Empire standart bearer as additional unit
4. I would make at least Inner Circle Knight sacred (actually, in my version it's planned to make Free Lances, who is normal knights, and Knights of the Orders, who is sacred...)
5. I would include both mounted and foot versions of Sigmarite clergy... Plus Arch-Lectors. Grand Theogonist, I think, can only be included as unique (?) Hero.
6. Idea of Wizards/Lords as summons I think just isn't right, but it's possible that it grants better balance (though making them capital only and costly could be restriction enough?). Or do you make it so for some different reason? With Skaven some units made as summons for Warlock Engineers was thematic for sure, but for Empire?
7. North forces I generally agree about, but maybe they better have chain mail, not plate armor (I mean infantry, not Knights, of course!)?
8. Maybe too many Knight Orders, especially if we remember that they are dedicated to different gods...
That's it for now.
In any case I plan to make at least some Warhammer-based nations coming autumn, but it would be fine to know reasons behind what you do..
