The patch notes say that Power Strikes is supposed to be granted every 20 seconds (which is what it was before, so I don't understand this).
But I'm having Power Strikes granted to me between 8 and 12 seconds now. Sometimes it's 8, 9, 10, 11, or 12. Completely random. Anyone else noticed this?
Edit: I just had the Power Strikes buff reapply after 1 second. I jabbed, then Tiger Palmed, and Power Strikes had already come back up and was available. Thinking this was a graphical bug, I RSK'd down to 1 Chi, and Jabbed again. Sure enough, back up to 4 Chi. To make sure THIS wasn't a graphical bug, I used BoK twice to make sure.
Edit 2: Just had samples of 4 seconds, 13 second, 2 second, 1 second, and 9 second refreshes of Power Strikes.
