I realize that this thread is 18 months old and about a bug, which is now fixed.
But on the topic of "spirit tap mechanics"...
Can anyone please confirm for me if Spirit Tap procs when you get the killing blow in PvP (from the honor gained)? Is that something that was implemented by 1.12.1 despite the tooltip not saying so?
I know it was there in Burning Crusade from playing on live, but in reviewing the patches (all of them) I cannot find when Bliz actually implemented this change.
