Dancer is feast or famine similar to how old Quickdraw setups used to be.

It gets extremely high damage with the caveat of being susceptible to several easily accessible hard counters. It's worth emphasizing that these disable Dancer almost entirely as a class.

Frozen completely shuts down a Dancer's entire kit with no counter play since Rest Beat got nerfed to be a movement skill and thus locked out with the rest of their kit. While Dance Hour can keep them safe from Immobilize/Clumsy for 3 rounds, its lengthy cooldown means if the fight goes beyond that they're helpless if they're inflicted afterwards. Grapple is similar to Frozen but offers the Dancer the ability to use a movement spell or some kind of knockback if their opponent is susceptible to it to free themselves--but unless they use a weapon with a knockback effect escaping a Grapple status will cost them all their Tempo.

Not to mention locking other players out of movement is generally powerful in and of itself, against Dancer it has the added bonus of effectively removing their class.

Dancer gibbing people as fast as old Quickdraws could is absolutely a problem, but so is how easily they can be Frozen + Clumsy/Immobilize spammed into being unplayable. Their lack of access to +hit is also an issue but that's more of a widespread problem with many classes, though Dancer doesn't have anything that ignores Evasion so they're SoL if their opponent already has or can attain an Evade number of 220-230~ or higher.

Nudging down the scalings for Thunder Steps and Ice Slide would be the easiest fixes for the damage Dancer can do, Idol Step is a weird case since it has a long cooldown and is only getting all that damage on one person reliably if there's only one person to hit. A compromise I could see for Idol Dance would be to actually increase its base scaling by 25% Light ATK but increase the same-hit penalty to 75% so hitting multiple targets is more valuable whilst wailing on one person does significantly less.

As for Dancer's Immobilize/Clumsy vulnerability, Dance Hour could afford to have its cooldown reduced by the amount of Tempo burned when its cast, as it isn't a Dance skill so it will remove all Tempo regardless at the moment. This means at max (6) Tempo, Dance Hour would go from 10 rounds cooldown to 4. If the status is applied before the Dancer can hit max Tempo the downtime will be higher as a result, so I don't think it'd be unfair.

tl;dr

Dancer does egregious damage with Ice Slide/Thunder Steps/Idol Step still but doesn't have much else going for it, being easily walled out of their class if prepared for.

I second all of this.
