I decided to main Dancer for Shadowbringers after hearing about it from the media tour and I've gotta say that I absolutely love the job. The feel and the flow of it really suits my gameplay tastes and the mobility makes it hard for me to want to play other jobs at times. That being said, nothing in this world is perfect and there are just a few changes I'd like to see come to Dancer hopefully before the next expansion.

1. Improvisation
I'm sure many people have already commented about this, but Improvisation feels like a horrible level 80 ability and it gets very little use as there are so few opportunities to use it effectively. I've heard many different ideas pitched about how to make the ability better but I think mine is a bit simpler and has the added benefit of actually adding to the Dancer's DPS. The change I'd make is that as soon as you activate the ability you should gain 50 Esprit. They could leave everything else about the ability the same and even remove the healing bonus if need be but by adding in this instant Esprit gain you can use the ability consistently inside of your burst windows while also still using it in that rare instance that you can't attack anything and people are stacked up.

2. Saber Dance
This change is needed regardless but ties directly into the previous change in that I'd like to see Saber Dance add 5 seconds to all of your currently proc'd abilities. Dancer is obviously designed to be a proc-based job but sometimes you get so many procs inside of your burst window that you have to sacrifice them in order to get the higher damage move out. If they make this change then you should be able to get all of your procs out and maximize four-fold feather generation.

And that's it! Assuming they don't buff the other jobs like crazy I don't think it needs any more personal damage buffs than this to bring it up to where it should be in a group composition but I also wouldn't hate a slight buff to their proc'd abilities if that's necessary for balance. I'm more concerned with keeping the overall flow of the job smooth like it is now.
