This has been there for a long time and has been reported by many players over in the Ranger discord. As far as I know people in Korea also report the same issue with Ranger's Razor Wind skill. The Problem: Razor Wind skill intermittently gets interrupted on its own and stuns your character for no reason. I've recorded a 7 min grind as Ranger using the skill as much as I could to show off the bug And here is a video of a Korean Ranger displaying the same bug https://clips.twitch.tv/PowerfulDarkWrenPartyTime It is a really annoying bug and has gotten me killed at least a couple of times now in Sycraia. It is very critical as it hinders our ability to grind efficiently by a lot.
