We are currently working on Lei Shen 25 heroic and are getting into phase 2 but seem to be faced with a much harder hitting first intermission than expected.
for those interested: logs can be found http://www.worldoflogs.com/reports/rt-gs6fu4xsmq73fjft/
mind, we have switched in/out some undergeared people at times just to show the fight.
The strategy we are (going to be) using at the moment, based on existing kill videos, is getting the Bouncing Orb coil highest on energy, followed by leveling the static shock. The issue we seem to be faced with is that both static shock and bouncing orbs are hitting us during intermission far harder than I had expected. At one point we had 6 persons stacked up on near full HP to soak a static shock, and lost 3 people which each took a give or take 500k HP hit from this (try 18 for those checking logs).
Note that we have all coils at around 90 energy or higher (none leveled) when we go into the intermission, so likely this is the source of the high damage output, but I do not see any way around that. Healing setup is more or less resto shaman, mistweaver, resto druid, disc priest (x2 at times), holy pala (x2 at times). During intermission we assign paladin and disc priest to solo heal a 6 man coil platform, and resto druid + mistweaver healing one side, shaman and disc priest other side. Classes with high defensives are assigned to the solo heal coil platforms.
Static shock solo soaking seems fairly hard on 25 man (atm only paladins, mages, hunters can solosoak if they have immunities up - high dmg mitigation classes like locks are getting hit for 1.4mil through 40% dmg reductions).
Defensive usage at the proper times is poor at the moment, but this can be fixed with more experience on when damage spikes is incoming.
Any tips are much appreciated, including if we do the leveling of coils incorrect.
