Dancer Flourish is badly designed and not actually enjoyable to use

[Harmonea]

HyoMin, my goodness, the post to which you're responding was not directed at you; go see who that poster quoted.

As for who the job flow should be balanced around, certainly not the top 5%. Job changes in SHB have been pushing jobs toward more general usability and a lower gap between the skill floor and skill ceiling. If forced to choose, SE very intentionally balances toward the middle of the pack, and this has clearly been their philosophy since late HW when they admitted their AST changes would make the job OP in the hands of a highly skilled player before going on to specify that the average player who played whatever card they got, not the top end who painstakingly fished for Balance between pulls, was their balance target.

While SE definitely wants things balanced for their most hardcore fans, it's not either-or; sometimes there's a way to please both, and that's usually by tweaking how the job flows to be usable from top to bottom rather than raw potency tweaks.

Which segues nicely into a general response to the thread:
As for the design of dancer itself, I would like more to DO during between-burst downtime. You go from "go ham on every button you can reach" to "shh shh shh don't touch anything unless it's about to cap," and it feels very constraining to me. Sometimes I end up using extra fan dances or saber dances because I'm bored and I'm... pretty sure I can still get back up to 3 feathers/50+ gauge before tech. Probably. Maybe. It's objectively the wrong choice, but I'm so desperate for stuff to do that it's damn near unconscious, like my fingers just DO it.

As for flourish itself, I find it difficult to manage optimally when things are busy. Popping it in the opener feels great as a way to get you some early feathers to use in that opening burst, but in subsequent burst windows, I find it hard as a middling player to make full use of all four GCD procs before they fall off when they're competing with a standard step and 3-4 saber dances. I'm not sure if that's my failing or flourish's design failing, but it doesn't feel good to play Sophie's choice with your procs.

I adore dancer as a job and would keep playing it for years even if nothing changes, but it could use a liiiiiittle ironing out.
