As far as I can tell, those are the most popular non-PHB subclasses for each class. And I don't know if you can make a poll big enough to fit every subclass in it, but I'm scared to try.
If you do try, and I don’t blame you a bit for not doing so

, perhaps you could tick the option that lets folk see results without voting? Not being a TT player, and having no familiarity with 5e outside BG3 and early Solasta, I have no opinions on any subclasses outside the PHB. But I’m still interested to see what other folk think is cool!
