So, Xanathars Guide leaves out the Bladesinger Wizard. Any thoughts on why?
Because it will be reprinted in the next supplement book.
My guess would be that since it theoretically only serves a single race, choosing a couple of the broader subclasses that more characters could take made more sense for them to re-release.
Is the Arcane Archer available to all races or restricted to (half)elves?
In my experience it’s definitely popular, it just evidently isn’t as popular as the Storm Sorcerer, Swashbuckler, Mastermind, or Sun Soul. The former two don’t surprise me, the latter two do. I was predicting the 4 most popular would be Storm Sorcerer, Swashbuckler, Bladesinger, and Arcana Domain. But what do I know? I’m just one DM, WotC has access to far more data.
I had the same prediction. Not that I actually wanted the Bladesinger reprinted, if I could have picked those four, I'd have chosen Storm Sorcerer, Swashbuckler, Undying Warlock and either Mastermind or Paladin of the Crown. I never heard anyone playing a Mastermind or commenting how interesting it is, so it was definitely a surprise to hear it's in the top-4 populars.
Notice how Crawford actually doesn't answer the question...
