I thought i'd shamelessly steal NIGHTBRINGER’s excellent idea but apply it to the better dwarf race (rather than the filthy goat fiddling darker variety) and look at comparing the dwarf core units.
The main reason i've done this, is because i've always gone back and forth over which is the better option to take, Longbeards or warriors. Specifically, GW warriors vs longbeards (or either shield or GW varieties) but i've done the stats for all options (matched against each other), just to cover them.
In each instance i've started with a unit of 30 warriors (with whatever loadout) and then matched the same number of points for the longbeards.
I've also added an additional column to give an idea of how many turns it would take to kill the other unit (I appreciate it doesn't take into account combat res/breaking etc but they’re dwarves, they will all be stubborn anyway )
Note: For the purposes of this post, i've ignored the quarrellers and thunders as they are the same as standard dwarf warriors but with ranged weapons.
As expected in a straight fight between non upgraded or just shield armoured warriors/beards, the longbeards win hands down, even taking into account the warriors greater numbers.
Things get more interesting when you look at GW warriors vs Shieldbeards. Although shieldbeards cause more wounds on average, the greater number of warriors turn this into a fairly even fight with the warriors just pipping the shield beards.
Again, with both units armed with GW's, the larger number of warriors make this a fairly even matchup, though this is very much dependent on the warriors charging, as the +1 Str makes a huge difference to them (allowing them to wound the Greatbeards on a 2+). The longbeards damage, doesn't change whether they charge of not, so overall they come out of this matchup as the better option.
We all know that dwarves are far superior to their fallen brethren but the question has always been how much so? It feels only right that this is the first question answered.
For this comparison, I've looked at our 3 best melee options (GW Warriors, Shieldbeards and Greatbeards) and matched then against the Infernal guard (with their 3 weapon options - Shield/Fireglaive and GW).
With the fireglaive armed guard, I added in a couple of lines to show the difference a short/long ranged stand and shoot reaction might have (answer - not much).
Great Weapon Warriors
As you can see, the warriors come out on top in every scenario, including if the fireglaives managed to stand and shoot. The +1 Str from charging does help but even if they are charged, they almost always come out on top (the great weapon vs great weapon ends up the same).
This matchup is more even. Vs the shield guard, both units would grind each other to dust no matter who charged. Vs the fireglaives and shieldbeards would win hands down, though the GW guard would likewise come out on top.
There aren't any close match ups here. The greatbeards win in every scenario. Their greater WS and base strength 6, help crush the dark dwarf armour.
