This brings up an interesting point that was kinda danced around earlier in this thread, that the standards by which potential new 5e material is being judged are very different than the standards by which the initital material in the Next playtest was judged. The PHB classes, subclasses, races, backgrounds, and all the rest, lived and died by how much they resonated with fans of previous editions. Nowadays, with the enormous influx of new players, they’re the ones UA material has to appeal to. And they don’t have the same baggage we do.
