I think the dwarves have a lot of potential, but at the moment they do not give you a lot to do
There are 0 rebels etc in the dwarf territory, meaning 0 to fight. And the kingdom almost never goes to war, in my experience, with another faction. And there are not many lords (which is understandable to not make the faction as powerful as the others, which is OK), but this means that you don't get any missions whatsoever. I have fully upgraded my village now that I got when joining the dwarves, but I have still seen 0 wars or had 0 fights with rebels in the territory. I just keep taking the quest in a dwarf tavern to cleanse a village of corrupt noble troops or something, as that is the only fight I am getting.
On the plus side! I really like the noble troops of the dwarves, they are really cool. But I kinda wish that the best infantry units had a shield, as that feels more stereotypical, and I want that for my slow dwarf units if I am going against a heavily ranged enemy, or even standing against an enemy cavalry charge.
There are 3 possible troop additions that I can think of to try broaden the Dwarf troop tree a bit:
1. A gunpowder unit, it can be a really bad gunpowder weapon with bad accuracy and long reload etc, but it would still be cool. Considering dwarves are generally seen as very high-tech it would be appropriate I think.
2. A medium-tier halberdier, without a shield. Being an upgrade from Kaikoth Warrior, making it parallel and on the same tier as the Kaikoth Mountain Warrior. The neighbours nearby, Hakkon, love their heavy cavalry, and it is natural that the dwarves would have developed a halberdier unit to try counter this. Alternatively you could even have a higher tier unit of the halberdier in the form of a unit similar to this unit in the back, in heavy gear and a spear + a large shield instead of using a halberd, running behind Thorin at 2:18:
3. When I think dwarf I think hammers.. Axes.. Pickaxes.. I don't think the Kaikoth Mountain Keeper fits the role that much, at least not RP-wise for me. I think something similar to this as a last-tier troop would be amazing, this unit being the Dragonslayers of Ered-Mithrin, from another mod to another game (Third Age Total War to Medieval 2 Total War):
I'm just feeling that when I play as dwarves I love the idea of a tight-knit shield wall formation going through the enemy, but that is not possible because currently the last-tier units, in the mountain keepers, have no shield (also I don't think the armor looks that dwarfish). I personally feel that the dwarves should have really strong armor and good shields, but not have that amazing weapon damage on their one-handed weapons.
I hope you don't take my feedback negatively, if any developer is reading this. I wouldn't take the time to write this usually for others mods, I am doing it here cause I LOVE this mod, and I see that you have an active mod team which are continuing to make this mod even more amazing. I have gone through all the top 10 mods apart from this one, for this game, and nothing hooked me, and then I saw this world. I seriously even like the lore of this, something I usually don't care about in new games (this is what made me reroll from my latest game, because I wanted to play as the dwarves now and take revenge on all the other races, especially the elves, when I figured out what they had done lore-wise to the dwarves).
So yea, I freaking love this mod, but please show some more love to dwarves! There are a lot of human factions out there to choose from, but only one dwarf faction, so for us dwarf-lovers it would be nice to have something big hehe. And I hope that there maybe is a new faction in the southeast in the future, bordering the dwarves via the open mountain pass at the east of the dwarves region, and also bordering the Drahara faction. This would make it more fun for the dwarves, if they had to deal with incursions by an aggressive faction in the desert etc.
