First it was Nightstalker that was bugged.
Now, it’s Blackjack that’s bugged, which doesn’t apply after a Blind is broken despite the tooltip saying “after Blind or Sap’s effect on them ends.” Or, if you’re a conspiracy nut, Blackjack was stealth nerfed to keep Blind in the dirt post 10.1 PvP changes.
The duration shift was crippling enough, now you can’t even use Blind as a sorta-offensive/defense, hampering damage or healing, like you can Dismantle (I.e. Dismantling a Warrior to stop Die By The Sword/Dismantling a Ret during wings).
Also, rumors of Triple Threat being bugged, but I got it to proc on my first swing in testing. False alarm on that front.
