Yeah I value @Zardnaar's thoughts on this and threads in general, but I think you're a bit closer to the mark here.Three extra attacks per long rest at level 3 and four at level 4 is non-trivial. Three or four attacks per short rest pretty good from when you get Font of Inspiration at level 5. And remember you also get the unarmoured defence at the same level.
Remember that you can also make an attack as part of this reaction thanks to Agile Strikes.
On the other hand a d8 to everyone's initiative can be stunningly good. If monsters last three rounds of PC attacks on average then beating them on initiative is the difference between them getting three rounds off and getting two. This is one of the strongest tier 2 abilties in the game, rivalled only by paladin auras.
I have difficulty not rating this as at worst an A-tier subclass. Four abilities for level 2, two of them pretty good? Two for level 6, one of them S-tier and the other just pretty good?
I mean, if we're being very objective, it's very hard to see how on an S to D scale, any Bard subclass that didn't actively wreck a feature or three could be less than a B, simply because the Bard chassis is that good (like most full casters in 5E, possibly all full casters in 5E 2024). Especially with Tandem Footwork.
I do think there's some needless finickity-ness of design in the Dance bard, and they should probably just straight-up get an extra attack with unarmed only at L6, but C seems a bit silly. Especially as we'll be looking at the Cs of some other classes which are just worse than that.
