Blood Tap doesn't work with Vamp Blood
I read on wowhead that you can make a macro that says something like this:
/cast blood tap
/cast vampiric blood
...Apparently, both blood tap and vamp blood are supposed to be off the global cd, so you should be able to use this macro to activate vamp blood when your blood runes are on cd.
However, when I try out this macro (when all my runes are on cd), I have to hit it twice -- once puts blood tap up, and the second puts vamp blood up. It does take my blood runes off cd in that even if I hit the macro when I have an 8 second cd on my blood runes, I can hit it again immediately and activate vamp blood.
So it's kind of useful in that way, but it would be even more useful if I could just hit it once. Is this possible?
