Sorry, I should have been more straightforward.
That's right : She's down
About the timing, after a few downs, our fastest (ok, I admit it's not that fast

) success was achieved in 9min05. Which is 58K/s dmg from the three groups devoted to Anashti. Our OT group is away managing adds pop.
We could gain a little bit more dps by replacing one healer with a dps, but managing the curse with only 4 healers (the 2 on the OT cannot help since they are too far) proved to be an issue for us.
