Went to the training dummy, spent a little while just learning an unholy spec dps rotation.
Changed to blood spec to check my dps against my other unholy spec, they are about on par in my gear and specs (I need to glyph better for unholy and it'll beat out blood on anything but single target fights as far as i can tell).
But when I was testing blood spec, I forgot to change out of unholy presence for some reason, and came out with 200 more dps than any previous test.
My rotation as blood is IT>PS>DS>HS>HS, DC dump, HS>HS>HS>HS, DC dump generally, I mix it up a little with DRW and ERW. Since I'm not the best dps in raids, I tend to keep Hysteria for our best dps on each fight... So I don't use it in testing.
I was getting ~2800 dps in unholy presence
2600 in blood presence
2500 as unholy in blood or unholy presence (albeit with better glyphs this will change)
Has anyone else noticed this?
I'm specced BcB and Necrosis in both specs. And I try to keep diseases up 100% (but this doesn't always happen, due to fight mechanics as we all know). I'm guessing that my overall dps was increased by those two talents, but somewhere in my gut and/or back of my mind this doesn't feel right. 200 dps, er.. ~7.5% overall dps increase from white dps, BCB and necrosis, but losing 15% damage overall?
Or am I being dim witted here and unholy presence reduces CD's on all runes too? The tooltip doesn't say that, and I don't seem to be able to find any concrete information about it.
