One thing i never really understood was Why doesn't our dance partner give us any buffs, Every class in the game has a personal buff surely we should gain access to it as well. If I'm giving you 5% you better give something back partner.
Cure waltz should have the regen from improv, scrap the improv ability its point less to dance a regen and a smallest little shield. Standard step should refresh fan dance 4 as well giving a more use out of it.
Devilment and Starfall on the same button with the animation delay gone (real mains will notice this)
Esprit should charge from our feathers being used as well.
Keep the Rng values the same you are a support class not a dps if you want to do big numbers go play >MCH

first this whole i need to Dance partner the SAM or RPR due to high dps needs to go, We are a support not a ideal to make one person a shiny star because you didn't get your kaiton back
Some ideas as dance partner could work.
DP- a Tank gives them 5% damage mit and you
DP- a Healer gives them 5% increase in healing.
DP- a caster for MP regen or a decrease in cast times (idk how this would work for BLM)
DP- a melee decreased time in GCD's


just some ideas and a opinion but i agree with some people here
it's a RNG class to not have a boring i hit 1.2.3 combo for a reason the RNG makes each instance/fight different.
