Heya. I just happened to stumble on this thread. :ggani: ( Don't ask how...)
So you're hireing people? I would like to join some team, and why not this one, methinks. Anyhoo, I'm quite a dwarf fanatic, i'm playing warhammer with drarves, an' making a campaign too (see my sig). so thats why i'd like to be part of this. I'll just ask this one time, and if you don't want/need my help i'll just bugger off. :ggani: I'm not too skilled in triggering, terraining and other WE stuff, but i'm practicing like a raving lunatic, and I have good ideas (IMO anyways...) on dwarfs.
here is few ideas for models, not entirely mine, but still pretty much boiled ready in my head.
Greybeards (or something): Dwarf veteran unit, that has hevier armor than the basic warrior, and carries a double handed warhammer. Ideal for safeguarding drarven kings. (because) Has a special ability called stubborness, which improves his stats when acting as a bodyguard to the king.
Instead of using mortar teams, wouldn't it be a good idea to make cannons (with crew, of course), because (at least what i think) didn't dwarfs invent blackpowder?
Bloodstalkers (or something): Dwarfs specialized in killing specific monsters quickly, each wielding a huge rune covered, doublehanded axes which do normal damage to other units and siege damage to big monsters.(like black dragons and ancient hydras.)
So here was three of my ideas. Let me know if you want me to help you. If not, i'll go an' pester someone else. | 
.....nah to silly. A spell i thought of is thaw, wgen u use this spell all units in the are get slowed down cuz the snow is heating upp. (thats what thaw means for people hwo didnt know, i didnt)
