The one thing I would like to see happen with DNC is this: Saber Dance has a 100% chance to grant Flourishing Fan Dance and a single Fourfold Feather when used.
This accomplishes a few things. Notably, it is essentially increasing the potency contribution of Saber Dance by 350 on single targets all without actually buffing the potency of Saber Dance. It maintains the flavor of the class by offering another opportunity for oGCD weaving, and allows more control in setting up a 4/4 feather entry into our TS burst window. It's also not "free" dps in the sense that we still have to track our resources and our procs or else we might waste something. Finally, it gives Saber Dance a bit more "oomph" in general. For being our final weaponskill (and arguably our "ultimate" skill since we get a passive at 78 and Improv is rarely used) it's rather boring in what it does. Tying Saber Dance into the rest of our kit gives it some nice synergy, and from a stylistic perspective it just makes sense. Here we are, filled to the brim with the vigor and passion of our dance partners, ready to unleash a feast for the eyes.
