Did the same dps in 559 item level, pretty much, you seem to have a lot of mastery though, I reforged all out, 80% mastery.
Also, evil eye of galakras is wasted for blood dps, whatever item level you have. Normal spark > normal evil eye, heroic spark > heroic evil eye, etc. etc.
The dead mage didn't do absolutely anything, just was there to get the achi and the save, anyway video inc in a few days, when I have time.
Was REALLY close in my case I have to say, I had full dps stuff except food (accidentally got stam), flask (had stam from zon'ozz hc) and potions not used, so probably 555 as minimum with correct buffs.
Also, nice soul reaper I got there!

But yes, really need to update for hagara, doable since so long, just those with heroic gear in 5.3 slacked (fnx and mionelol) "I don't care about her, she's doable and presents no challenge whatsoever", so we ended up doing it in 5.4!
