Just started on leveling my DNC and came upon a bit of a strange oversight from the dev team.
Whilst pre-assigning buttons to my hotbar and getting to understand the class, I was struggling to understand how I would proc threefold fan dance for Fan Dance II. Only after opening the job guide on the web to see tooltips for max level and then using ctrl+f to search for that phrase did I see it has a 50% chance to proc from Fan Dance I/II.
The inconsistency here is there is no trait for level 66 that coincides with this however. In all other cases that I'm aware of for other jobs, any time a tooltip updates like that there is a connected trait that shows the update. As of now, with just in-game information there is no clear way to see this change has happened unless you're specifically re-reading all your tooltips after each level up..
Hell BRD/ARC has a trait at level 2 for it!
I would expect something like a level 66 trait
