I can totally agree to that. I would not at all like to see mounts. Slow and steady is the Dwarf way. Steam punk intrigues me, but is by no means essential to the growth of the race.
Ever wonder why with all the technology, Dwarves have never used weapon teams like Skaven? Seems viable to me, although they would be reliably made.
You could argue that timeline advances with each new release......so if they phased out things like crossbows and bolt throwers, it would make sense. Even Dwarves have advanced, albeit slowly.
I think that any changes would be good. My concern would be to keeping the slow and steady dwarvish feel to the army. I would also like to see them stop losing in the lore.
If I can win on the table top, then my army should also win in the pages and pages of lore.
