The thing with the dwarf is they don't take ANY headshot damage. With all the other races you can cause a significant amount more damage by shooting them in the head with any weapon, but the dwarf takes the same amount of damage anywhere on his body.
Not to mention if he's near a tree he can heal pretty quick. If you're sniping from a distance they can hide a tree behind a wall and heal through the wall and you might not even see the tree. I used to do that on Power Station. Kept me healed and didn't hinder my vision (Nothing like a big freakin tree in front of you while you're trying to snipe!)
