MCH are doing fine because of the buff to GB. We wouldn't be doing as well if that didn't happen.

Right now, I'm actually wondering how savage will be. I do find that AoEs kill our dos quite a bit. For example, on Bis Ex, I've taken to dropping GB altogether during third phase (and sometimes second) because of all the AoE and tornadoes we have to dodge. Not to mention killing bubbles. I tried it once using GB full time and ended up at 588 dps, which was crap.
