"Regarding Glyph of Blackout Kick: It will return, but as the glyph is completely missing from game data, it can't be added via hotfix. It'll have to wait for a content patch. Sorry"
I'm not even mad about the 5% RSK nerf now that I saw that. The bleed effect from blackout kick adds up and never wasted, therefore it will be super effective spaming BoK with Serenity up without worrying being behind the target. Hope we will not have to wait too much about that content patch!
Blackout kick actually got a huge buff with the removal of resilience, the way the dot used to work it would double dip resilience, one pass from the blackout kick damage reduction and then another pass reducing the damage of the dot.
the heal from blackout kick is actually worth keeping around if you are good at character positioning, since the heal isnt reduced by resilience and battle fatigue anymore, so when playing defensively you have the heal from the front and when playing offensively hit your target from behind.
