One of my main gripes with Dancer is that it could use way more consistency. I feel like that would make it easier to balance in the damage department as well as improve the overall flow of the job. instead of trying to balance around a 50% proc... that procs another 50% proc... that procs... yet another 50% proc? Getting those occasional 1 2 spams without anything is rough. Finally proccing a 3 or 4 and not getting a feather off of it also feels pretty bad. This change would also make it easier to set up for burst windows since you could have 4 feathers built up readily for a rapid burst phase.

Improvisation for me so far has literally been an insti-cancel regen tool for my tanks on large pulls to help them out a little. There are not a lot of moments where I think to myself... You know what, let me stand here for 15 seconds and dance around for a 10% shield. I get it. It's there for downtime. But most fights don't have downtime, and definitely not enough to stand in place for 15 seconds while it charges up... for a measily 10% shield lol. You could just make this a regen button and I honestly would never feel the difference. One thing I think they could do with this ability, that could actually be really cool, is take inspiration from FFXI's dancer and turn Improvisation into Haste Samba.

Haste Samba: While you are charging up, your whole party receives a 15% reduction to their cast times and recasts. Basically a party Huton that would suppliment the lack of you dealing personal damage while it charges. Keep the stacking system up to 4 charges, but change it to unload a massive attack as a finisher. Take a note out of Reaper's book and make it 1000 potency at 4 stacks (250, 500, 750, 1000). This way, it could almost act like an additional burst phase for everyone but the Dancer, but you still get a strong attack out of it and some nice RDPS icing on the cake. Honestly, I wouldn't mind Dancer being behind as far as it is on damage if it could pull some sort of effect like this for the entire alliance to make up that difference.
