Right? I've been dedicated and lucky and have 850 ilvl atm my partner heals, she's ~844. We take our friends into mythics so they can skip heroics, all of them around 815. Just a few days ago we did N.Lair with 2 dps doing less than 100k, the other was pulling a bit better(~130 single target) by virtue of being a hunter and I suspect he knows his rotation better.
