We are still progressing with this, I am in the 2nd, 4th, 8th and 10th groups, so same as above. I have used SW:I, PI, and DS. PI is used on Ji-Kun at pull, I haven't had it line up badly and we don't need extra dps on nests so I am happy with that.
For nests I will DS as I land, SW:P three, and focus the last. DP3 and MF:I just wrecks them. Usually by the time mine is dead my WW Monk buddy has killed his and dots and cleave have the other two around 50. We mop those up and then switch to the guardian if the tank and cleave hasn't finished it. For the pairs we just focus one each and dot/cleave to the other. We have a habitual understanding that he goes left and I go right for all sets. Works exceptionally well. We're waiting on our healers to get across that they can't miss nests, and the dps in general needs to get better at nutriment. But nests are not our issue.
