I think the value of the dwarf warrior is understated as people focus on human warriors. Yes, free sci w/FoK is nice and +44% automatic OME in war is awesome...but a dwarf warrior can easily match a lot of OME using TG (easier than other races with the increase BE).

Ultimately the human can stay ahead on OME also focusing on TG (though much more % land for TG than dwarves need to achieve respective bonuses), but the dwarf doesn't suffer -20% gains...they only have to worry about a little food, which can easily be donated. Dwarf also gets PF, while human doesn't, so KD that has dwarf warriors doesn't have to be concerned with having clerics for casting PF.
