While [MENTION=11697]Shemeska[/MENTION] and I often disagree on the value of sticking with old-edition lore, in this case I think we're very much on the same page. I really don't see the upside in tying Asmodeus into the Yugoloths' creation. Honestly, I think Asmodeus already has an unfair amount of focus/influence, as compared to other arch-fiends. He doesn't need any more, and the Yugoloths don't need to have been "devil lite."
But then, I'm also irked that the ultraloth is markedly less powerful than the balor and pit fiend, and that we got mention of the General of Gehenna--who's described as an extra-powerful ultraloth, nothing more unique--and we didn't get Anthraxus. (Who, if we're going back to 1e, was--by XP value--actually more dangerous than Demogorgon or Asmodeus.
But I'm not bitter.
We're very much on the same page. I think most of the time we're probably on the same page to be honest, with the exception of a few particular situations (and honestly I'd be totally cool with returning Anthraxus to the top of Khin-Oin, provided that it be given a solid treatment rather than happening in a line or two in a supplement. He's a classic character and his return would deserve better).
This particular bit of 5e lore regarding the 'loths solidly conflicts with the stated intention of 5e embracing D&D's history and past editions' material. It's really disappointing for me, right up there with the 5e tiefling.
Of course if an eventual MotP acknowledges the depth of 2e/3e lore on the 'loths and their origins by presenting them as options that would help a lot, same as seeing 2e/3e style wildly-variable tieflings returned to the game (and called tieflings). 5e's focus should be on presenting options that embrace the game's unique history rather than rewriting it with the flavor of the week, and if they need subject matter junkies for various areas, they're out there. I would happily lore check for WotC anything involving the 'loths.
