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?
My 4-set bonus just reduces the cd on vamp blood by 10 seconds...So I guess having blood tap bound to vamp blood is useless for me? I have had it bound to vamp blood ever since I got both just because I thought it instantly made you able to use vamp blood when you had no blood runes :X.
It's possible that it worked the way you thought it did at one time, but it does not now. I had never tried the macro until I read your post. The 4-piece is the only reason I can think of to use that macro the way it currently works without spamming it. If you really want to use it, that is an option. Just spam the button untill everything fires.
^ Ok, thank you for your help . I think I'll just keep it as is so I don't have to worry about not having a blood rune up -- even if I have to hit the button twice, it beats waiting 8 seconds for the runes to come off cd.

I think that's the point of this macro, to have Vamp Blood always available. Dunno why it doesn't work, never tried this. In blood spec you usually have some blood or death rune available because of single rune Heart Strike, so it isn't that big deal.
