The 20 load capacity doesn't even make sense when I can just send everything to camp with a click of the mouse.
So I basically have proficiency with light armor and polearms as the only things humans have going for them.
I suspect the weight capacity also factors into throwing capabilities. Larian seems to value the ability to toss dwarves as a key component to the game. As such +20 to throwing probably seems like a big deal to them.
