It seems Twisting Blades was shadow nerfed and it doesn’t work correctly atm it seems.
It says in-game (Advanced Twisting Blades):
When your Twisting Blades return, your active Cooldowns are reduced by 0.10 second per enemy they passed through, up to 2 seconds.
Unfortunately, it seems it only gives the CDR for the first enemy it hits/sometimes it resets nothing, even after passing through a lot of monsters.
EDIT:
So after some people checked it in Discord it seems it is 2sec CD per skill? I don’t know? Which would be absolutely trash.
It seems it works but it’s not a lot at all and kills this class completely. I started this class to have mobility and not just facetank like other classes. Now, it still feels like someone cut off the legs of the Rogue.
Please revert this change, Blizzard. Or reduce the dmg of TB a bit and increase it to 0.15/0.20 and remove the 2 sec cap. And also add all the information on how a skill exactly works.
