We should probably ditch the UA ones first...
It's as good a reason to downvote something as any other. But I wonder if people would actually be able to tell me which ones were
Unearthed Arcana and which ones weren't, if I didn't cite the sources up top.
That might be an interesting experiment for future threads. I could "accidentally" label something as
Unearthed Arcana instead of
Xanathar's or whatever, and see if people downvote it out of reflex without even checking.
Also: many of the
Unearthed Arcana versions are superior to the ones that made it into print elsewhere. Just sayin'.
