Plus the fact that more than a few of the Wandenreich have used a sword of some kind (e.g. Bambietta and her Zulqifar, Yhwach and his TWO swords, Haschwalth and his longsword) when Uryu explicitly stated relatively early on that Quincy don't use swords, only bows and arrows. So it seems like the Wandenreich's Quincy have progressed past more than just the Letzt Stil.
