What is this class design of Dancer?

[Driavna]

I think the procs trigger often enough that dependability won't be a problem.

On averages you are right but from time to times you will get extreme bad luck / good luck scenarios (like failing all gathering attempts in a row with 95% success rate!). For very competitive people I guessing is not an ideal class, for your regular player the main problem will be finding a spot.

Ooh, I could even make a mistake without having to wait 30-45 seconds to recover from it and get back to doing decent damage? That sounds awesome!

Yes, is not like ninja at all. Mistakes will cost you damage, but nothing you can't really recover. (Fail, or delay, a trick attack is a big deal. Needing a few steps more to complete a dance, not so much).
