The 101 Duelist skill "Duelist Wrath" has been bugged on innova for quite some time. Recently, DIL confirmed that korea has replicated the bug on their side.
The bug was: Instead of giving +20% P Skill Crit Rate, it was giving -20% P Skill Crit rate. It was acting as a nerf essentially eliminating the class from usefulness. This bug ONLY existed on innova.
This patch note you reference is ONLY present on Innova's patch notes. Also, after talking with some players on Core, they have done tests to that show the Duelist's skill was fixed with this update.
You all are getting upset about a patch note that isnt even about yuls. There is a reason why different regions get different patch notes.
The yul crit rate is not capped. I can confirm with how my 112 yul, 107 dex performs with my skills changed to focus from break.
edit 2: my othel behaves the same. it always crits.
