I am taking otherworldly amounts of damage on H Yor'sahj. We're having issues with the stoplight combination (red, yellow, green and black; killing green). During this combination, I seem to be taking more damage than needed. I am directly under his feet cleaving the Forgotten Ones with multi-shot from Yor'sahj himself and rotating raptor strike, using deterrence when I'm getting too low.
We don't run logs and I don't have any data left over from last night but we're going in again tonight. I'm having a feeling that our healing (professional rhymes) is a bit dodgy, as well.
