Finally cleared this this past weekend (got stuck on Un'sok for a bit, sigh). Copied this post over from my update on Maintankadin.
Sometimes dissonance fields seem to randomly go down at the same rate even with one player with Cry inside the designated field and chaincasting. This happened ~ 4 times in 20 attempts, and was extremely disruptive, not sure if anyone can shed any light here. We were VERY careful not to have people/pets/doomguards/anything-that-shouldnt-be-there in the un-designated field after the first time this happened. Bug? Or did I miss something?
Once the energy fields are ~20% energy apart that was sufficient for our healing crew (3-healed it) to top off in between.
Did not find any particular rhythm to the Cry/Dissonance such that we could easily have all Cry damage soaked, it seems to vary a fair bit as the Dissonance fields lose energy at unpredictable rates. Devo Aura is quite helpful to mitigate part of a Cry that isn't soaked in a Dissonance field.
Sometimes Dissonance fields will just sit and do nothing for up to 10 seconds after reaching 0 health. Basically, dont drop a raid CD until the explosion has actually occured.
Tanks should be ready to burn major CDs on the pickup of this phase, as they have to take 10 - 15 secs of all 4 adds (assuming you split evenly) before the Windblades begin to fixate.
Of the 8 adds, the 6 Windblades CAN be stunned, which we found key in helping to minimize tank damage. Note that while they are fixating they cannot be stunned.
You have plenty of time on phase 2, such that you should always be able to form two full traps, i.e. one for each of the large adds. We kept 1 Windblade alive along with the 2 large adds, to ensure the phase wouldn't end prematurely. This is a great time for your healers to regen some mana/focus etc, since tank damage from one large add each is non-existant.
At the end of phase 2, both tanks should have the poison soaked debuff which lasts 2 minutes. Every DPS in your raid should get this by running over them, before the phase ends. ALL dps benefit from this buff.
Phase 1 Redux:
Nothing special, but while your tanks still have poison-soaked, the OT should periodically run through the raid over the DPS, giving them a fresh 30 buff any time it expires.
Nothing special, tremor totem/Fear wards are nice if you have them available, but really so long as healers are quick on dispels this phase is a non-issue.
Edit: Probably worth mentioning, when you transition from P1redux into P3, you really cant have a dissonance field up. We did this and the field exploded ~ 3 secs after P3 started, perfectly coinciding with her first raid-wide health-reduction cast, neatly one-shotting all of us hard-enrage style XD
