I just got a blood to drop tonight, 15 May 2006.
I am a level 67 enchanter, and the charming was an absolute piece of cake. The things hit for so little that I could pull one and let it beat on me while I cast charm. They never even got through Arcane Rune before the charm landed. Charm always lasted very long (I always pulled with Tashan).
The battles take for freakin' ever because the mobs have such high health, but it is an absolute cakewalk. It just takes time.
