Very true. But, the lack of references of Qrow by Yang is evidence, although flimsy, to the idea that the two of them are only connected via Ruby. The best way for us to tell this would be once he makes an on-screen appearance - I'm going out on a limb to predict gothic-styled clothing and a lot of black. Also, we only know that Qrow is armed with a scythe, not that he's knowledgeable in hand-to-hand fighting, which is why my theory hinted that Yang learned from their father, and not Qrow.

In the way of her physical build she's clearly more suited to getting in close than Ruby is - she is both taller and broader than the younger girl, which is advantageous in a close-quarters fight.
