Why are there barely any dwarf paladins?

So I want to start a pally and I'm debating between human vs dwarf. I typically like to min max these little things so after looking online a bit dwarf seems to be what people recommend most because of stoneform.

My question is, how come I never see any dwarf pally almost ever? Is it as simple as people not really caring and picking the race based on aesthetic or am I missing something about humans that makes them better? I'm on nightslayer so I thought the dwarf racial would be even more important.
