Unless i misunderstood, forming a battle line here means they will also be beefy in melee combat as we've seen from Streltski who have better stats than Thunderers despite the latter being 197 year old dwarfs with dedicated melee equipment and the former utilising some weird gun in melee while being totally human like my uncle.
Personally i always disliked the dwarfs being too reliant on ranged damage. Yes they are cheap and cost effective just like every other cheap ranged troop, and this can also cause issues against some factions due to how spammy they can be. Fill the battlefield with 500 gold armored, shielded ranged troops with 160 range and let them pepper everything - what's not to like? Too much quantity over quality.
Yet this is not how they were in any source. Their cheapest ranged troops had the same melee stats as Dwarf Warriors in TT so you could actually form a proper hybrid frontline from ranged troops. So far Kislev troops "sound" like how dwarfs should've been. Yet in TW, in default state
- 700 gold armored Thunderers get murdered by 300g Goblins or similar before even dishing out 150g worth of melee damage
- Irondrakes, who were supposed to be sidegrades to Ironbreakers, have absolute zero melee capability
- Rangers were stripped from their armor and hence they are even worse than Quarrelers in melee, receiving heavy losses even against some malnourished Skavenslaves
- Bugman's Rangers, who appeared without Bugman, are the only ranged unit that is somehow close to being hybrid, yet they too barely survive against any cheap chaff
This also gets exacerbated in campaign where melee troops get further buffed, but the above mentioned units don't benefit from melee buffs, and become even worse in melee. This situation is also one of the reasons that "TW Dwarfs" are so boxy and campy; because their ranged troops require constant babysitting, and their vanguard units were heavily tier nerfed. Not to mention lack of various unit runes heavilty diminishing their playstyle. Gotta admit though, it's quite an achievement to make a faction play more limited than they could in TT, yet not so surprising given the attention they have gotten so far.
Title may sound like a rant, but it's actually a sound criticism which has been brought up many times by various other users before.
