Hmmm, thanks for the advice. We have a handful of raiders with decent defensives (rogue, hpal, warlock, mage) but at the same time, our guild ilvl is ~527 so I feel our gear is slightly under-average/on-par with where we should be at our current progression of 5/13.
Not sure if that falls into the "low gear" category that Nairobi mentioned, but I think we may try to push through Jin/Horridon and Tortos/Meg trash quickly so we can get a few pulls on both Council and Meg.
I think IQ took us 2-3 nights, but we had limited attempts our first night and it only took us about 7 pulls or so last night to get him down (maybe ~20 total). I was hoping Twins would be in the same boat, but we had a new "artist" last night so maybe it was just an issue with timing the aspect buffs.
