Dwarven warbands need restructuring so that they don't just castle and gunline.

Making random charges, as described in my other thread will allow dwarves to charge more often. This will be good for the game, because it will allow dwarves to diversity some more.

Another idea i had would be to give dwarven a steam-powered jetpack (called jumppack) as special equipment.
Some kind of dice rolls are needed to activate it.
If all goes well, the dwarf flies 12", possible with some kind of charge bonus for jumping. (Does anyone know the charge rules for assault marines?)
However, if it goes wrong, the jump back may explode and deal damage to the wielder, stops working, or if a 6" is rolled for misfires, the jump becomes even more devasting when charging.

Another thing that would really make dwarves more mordheim-suitable would be if they had an auxiliary henchman race, like chaos dwarves have hobgoblins but there is of yet no such race in the WHFB universe. one could perhaps steal gnomes from D&D but other ideas might be better.
