Just from a random wsg I was queued into in the 70-79 range. (I was 76 here)
Also something interesting to note: If you click off your Shadow of Death ghouls bug when you die and come back as a ghoul, it doesn't count as a 'death' in BGs. Probably just a bug.
In case anyone is wondering, I'm currently running this spec.
I'm just messing around with talents right now, trying to get a good feel for them on live. I'm pretty much convinced at this point that mark of blood is really only good in some 2v2 scenarios or in duels. I'm probably going to drop it, and the subsequent points required to get it, for more points in unholy.
I will be uploading the fraps footage of this BG just for kicks as well later today.
On a final note, is seems that no one on the live forums cares to hear what you have to say unless you're complaining about something. Figures.
