Running a similiar comp we usually run for Fractals (slightly modified), we managed to get CM going very smoothly. Some pointers/tips for what's happening here:
I (the Daredevil) am naturally running a bunch of CC, that's not unusual. Basilisk Venom and Palm Strike are fantastic for the many breakbars throughout. I'm also liberally using Signet of Agility on Ensolyss during his big combos to ensure everyone has enough endurance to dodge all the hazards. I'm also going to be traiting it in future for a lower cooldown and to give myself some extra Might to make up for downtime on the PS Warrior since Ensolyss moves so often that it's tough to keep 25 permanently (this just replaces 7% crit damage so is no big deal). I'm also liberally using skill 4 on Staff to keep Vulnerability high, as Ensolyss and MAMA to a lesser extent cannot be constantly wailed on so can't always be at 25.
The Reaper is handling a bunch of condis that come our way as normal, but also has slightly changed up the build for a bunch of quick corruptions so that adds and the boss never have Protection for more than a second or two. The Chrono sword takes away the boon slowly from the boss but it's nice to just keep Protection as low as possible so those extra few seconds count.
Chrono is running Moa. I'm not sure if there's anything else in particular of note, it may just be meta as usual.
The Tempest is running support, so healing and boons. Tempest healing is insane and has huge area effects so it's easier to land than Druid. Seeing as there are no enrage timers or major DPS checks (only at Siax) it wasn't necessary to get GOTL going all the time from a Druid, so it was fine. I believe he was using the "gain 10 endurance on applying Vigor" trait so everyone was getting a crapton of dodges for evading all the big stuff, while I helped with my signet.
Power PS Warrior was as normal with Mace/Shield for CC, though they took Outrage instead of Signet of Fury just in case Ensolyss knocked them badly.
