You do realize that the Stern Ritter's consist of 26 Captain-class Quincy right? With five of them being on par as Advanced Captains to even beyond that, given that they could tangle with members of the Royal Guard. So the idea that captains dont grow on tree's is a bit incorrect given how many were around for Yhwach.
