blood spec retail 3.3 end of patch bla bla
You give me time machine, i wana play wotlk retail too, like you guys
show me someething how blood is doing RIGHT NOW, HERE ON WARMANE, oh you cant because blood with BiS gear does 13k damage.
I'm sorry for giving people relevant and current information, not some "as it should or would" dream world in which you apparently are.
But yes, you are right, there was a blood bubble, tough rarely who played it and better results than unholy or even frost was even more rare.
In theories, sims and crap that does not fully reflect actual game, blood might be better.
So good luck with farming reagents for time machine.
