I'll try to make this as short and to the point as possible.
I was previously running the deep blood with a pet spec on the test realm and was averaging a little over 2700 dps on the boss test dummy in Ebon Hold.
With the changes they've made recently (no more pet for deep blood, DRW nerf, DS nerf), I could not even break 2000 dps on the same test dummy. I was bearly breaking 1900 dps.
I know blood needed some toning down, but a nearly 1000 dps nerf? Are you kidding me?
As far as the other specs. I still can't test unholy due to the lack of glyphs, but I was getting around 2900 dps in Frost.
Blizzard has completely and utterly destroyed the blood spec. With this nerf, I don't even thing you could hold enough aggro to do a blood tanking spec now. Ridiculous. >
