Gonna be really, really hard picking between Glamour and Dance.
And maybe more than any other class, it feels like a party of 4 Bards with each of the subclasses would be an extremely capable group. Nice mix of magic and matial early, expertise covers a lot of skill check ground, and once they hit level 10 they have access to a massive range of spells to deal with higher level threats.
Edit: Once question I have. Do Bards now prepare spells after a long rest (like Clerics, Druids and Wizards), or can they just swap out 1 (or more) when they level up? Wasn't clear in the video.
