Alrighty I will actually add something now.
Pat I don't believe anyone is doubting the exsistance of Blood Magi in wow as they do exist. And yes they are, for the most part, not like Blood Magi from other sources. The only ones that actively participate in the consumption of blood are the Fel users. But as for the actual ability to RP as a Blood Magi, as you are describing, would be quite acceptable. Which has been stated.
It seems now that we are just digressing into pointless arguing over the actual naming of the, for lack of a better word, "class". So I think we should just leave it as most people find the term Hemomancer is a little silly and/or not as pleasing to the ears as other terms such as Blood Magi.
I would rather not have to request a lock over something so foolish so lets just let it lay unless you have something meaningful and constructive to add.
