The problem is when you're out of combat the only way to proc blade barrier is using vampiric blood+ rune tap, if you use blood boil and death and decay or double blood boil it will not trigger a talent.
Ok, so I've tried few combinations out of combat
rune tap + vampiric blood after = no blade barrier
vampiric blood + rune tap = blade barrier on
blood boil + blood boil = no blade barrier
death and decay + blood boil = no blade barrier
Seems like no matter what if you use rune tap second you will get blade barrier only.
How it should work:
Should always proc when 2 blood runes are on cooldown.
