Diva - Am I going for the correct stats?

[Diva]

I need help with my damage output.
In heroics I deal approximately 45k - 55k DPS depending on the fight.
With Bloodlust/Time Warp my DPS reaches to about 70k - 80k.

The thing is, I see some players with gear inferior to mine, dishing out 90k - 100k DPS (especially warriors..)

So, is there anything I've done wrong?

Hey there.
1st - Get Mind spike glyph.
2nd - Get as much int as possible. I tried to gem haste, i got my 7586 as goblin but my dps droped. Now i sit at 55-70k avg on a boss fight (raid) and 100-200k on trash (Use halo, multidoting and mind sear)
