The
survey for this UA is up, and there are some new additions to refine the questionnaire. Besides adding a Don't Know/Not Interested option to the questions there are new questions asking if you actually playtested the subclass, if you've played the related class in the 5e era, and how interested you are in playing the subclass in a game.
I for one applaud the addition of these refinements. It lets me easily indicate that I'm neither particularly inspired by the Spirits Bard or interested in Bards in general, while I have experience playing Warlocks and would roll a new one to use the Undead Patron. It'll also help separate feedback from people who are eyeballing these subclasses in the abstract versus those who've gone the extra mile to try them in play.
