I am in Dynamis Xarc right now, just obtained Etoile Casaque. So far I am noticing that every Violent Flourish I am doing, stun procs 100% of the time. I have yet to see a single one miss. I will update with more information as we progress.
Update: One missed, but I am noticing a much higher procrate than normal on the stuns.
