Well here are some of my observations about dwarfs, and their problem.
1. Economy
Most of dwarf income is from farming, and that's bad, big farms, great population grow ends with squalor, devastation, and low income. In my opinion main dwarf income need to come from mining, tradings is not a good option too, great orks stack marching on dwarven lands will reduce their income. Empire factions can place 3-4 full stack armys with no problems, dwarf have problems with only 2.
Why dwarfs can't recruit units in towns, and build there most of their buildings, i know that they are underground race, but well they live in Empire, so it obvious that they can handel them self on surface. You can implement the cultular tradition to the game, if you do not wont to make themy spread to easyli
2. Overpower enemys.
Orks are to overpowerd, they got insane good units like destroyers, blac orks, and pretty good big uns. All of them got 2hp, so they are preaty imute to range weapns, main dwarf weapon.
This are the military statistic from my reikland campaign, turn 52, orks are insane powerfull.
And here is a map from this game 10 turn before
And this is from my dwarf campaign, also with map of the world.
Orks are not so powerfull like in reik campaign, but i got great battles with them every turn, most of the time wining.
And chaos attack is olso too powerful.
3. Dwarf units.
First of all they got tired early, let me show you.
Dwarf warriors runing on battlefiled, i used yellow color to mark first running turn, and red to mark second, screen is made when they got exehausted.
same thing with empire swordman.
As you can see they make greater distans than a dwarf, and dwarfs got good stamina, swordmans don't. Dwarfs get exehaust quicker in fight too, i don't know, maby this is because of their smaller models, and becuse of that they make more steps. I don't know but this is iritating.
Second thing, lack of missle warriors capable to fire from walls, when you fight with orks it's not so flustrating, because they are nearly impenetrable, but whe you fight with other enemys, like sylvania, gobs, or chaos, it is nightmare for defensive race.
Third thing, dwarf units, are weak, they main weapon, such as warriors, axe warriors and quallerels are too weak compare too other races. They got the hardest infantry in Warhammer lore, but here, they are just a bunch of easy kill shortis. And i'am speaking about TT, and RPG World describes.
And last thing, why the don't have a option to get mercenaries? It'a a well know fact that dwarfs using merc units, instead of losing their priceless brothers.
4. About AI.
Dwarfs got homes on mountins, AI got problem moving units there, so we ending in Karaz-a-Karak, Karak Eight Peeks, and Zhufbar sticking together, Karak Kadrin, and Hirn left alone. Karaz-a-Karak is losing angainst chaos, and Karak 8'peeks 9 form 10 times is getting owned by gobs. If you wont to dwarfs too be alive, make them a Karak in middle mountains, place there 1 family member. They do not get any cav, so with their not so good infantry they are often losing battles when AI manage them, and well orks wins almoust all AI battles, coz they are OP
It's all this time, maby i will find some time later, and sorry for my awful english.
