Bladesman Inowari "Wavedancing" not functioning

As the title of the threat states, I cannot under any circumstances get Bladesman Inowari’s ultimate ability “Wavedancing” to work.

He will cast a 30 second duration buff on my character called “Wavedancing” which describes itself as “Coordinating Attacks” but there is no coordination, no extra damage outside autoattacking and Waveblade (different ability) and certainly no disorientation, which is part of what Wavedancing is supposed to do. (Wavedancing says Inowari will coordinate attacks with me, attacking when I attack doing physical damage and disorienting the target.)

Please look into this, as I spent a long time leveling Inowari in order to get Wavedancing – yet it doesn’t work. Feels bad, man.

And just to be comprehensive: I’ve asked at least 5 people with Inowari at level 15+ – who I do not know and who almost certainly don’t know each other – if their Bladesman Inowari’s “Wavedancing” ability was working. Every single person reported back that they have never seen the ability work, and several weren’t even aware that it existed. This is a widespread issue.

Bumping this thread. This is a major issue that I can’t seem to get any attention on, even though I’ve reported in-game and on 3 different subforums.

I’d just appreciate some Blizzard confirmation, instead of hearing players like me say over and over, “Yeah it doesn’t work for me either.” Discouraging after a while…

I want to see Wavedancing work correctly.
