Hold your 3rd use of Force of Natureand your 2nd use of CA/Incarnation to make use of both inside lust for intermission damage amp.
Pool AP for easy movement if you're targeted by Spew Oil.
Can use Mass Entanglementon the Support Rig adds in intermission on mythic difficulty.
Use first set of cooldowns on pull, and if necessary, hold Berserk/Convoke the Spirits for intermissions. Continue to use Tiger's Furyon cooldown.
Use Barkskinwhen soaking Oil Canister on mythic difficulty.
You can back away from the boss and utilize Wild Chargein Cat Formto get behind the boss quickly for intermission, if there is still an oil puddle in the way.
Use Predatory Swiftnessproc on Entangling Rootsduring intermission to keep Support Rig's away from melee. If you're on the first one, you'll need to refresh later in the phase.
For the third Support Rig of each phase, you can use Mass Entanglementor Ursol's Vortexpaired with Entangling Vortexand it will last long enough.

Cauldron of Carnage

Can swap out Stellar Flarefor Wild Surgesif it makes the fight easier for you. Stellar Flarecan gain some value in intermission if you manage to keep it up on both targets.
On Torq (gorilla) side, pool AP for easier movement to better dodge swirlies before boss uses Thunderdrum Salvo. Do not get cut off and don't cut off others with your swirlie!
Can use Mass Entanglementon the Voltaic Image adds as they fixate players.
On Flarendo (dino) side, position close to boss and Wild Chargeto the bomb soak.
During the intermissions, make sure to dot up both Flarendo and Torq.
After intermissions, use Skull Bashor Wild Chargeto charge to whichever boss you are attacking. Be mindful of the ground when you do so.
On Torq (gorilla) side, stack with melee, and stagger Pool Drops in a predictable direction across the boss.
Any Voltaic Images you miss with Mass Entanglementcan instead be rooted with Entangling Roots, using Predatory Swiftnessprocs.
If you're forced out of melee on Flarendo (dino) side, take advantage of Lunar Inspiration, bad casts and overcapping combo points is better than overcapping energy. (That being said, try to not be stuck out of melee)
Use defensives for Scrapbomb detonations. This will still damage you on Torq's side of the arena.

Rik Reverb

Commit defensives when soaking Amplifier Pylons.
On mythic difficulty, be proactive when targeted by Faulty Zap to break the shield on the pylons.
The boss is immune during the intermission, save cooldowns for after it ends!
Intermissions are a superb time to use Bear Forminto Frenzied Regeneration.
When the boss casts Sparkblast Ignition, try to Primal Wrathas many Pyrotechnics as you can.

Stix Bunkjunker

You should probably play Balance instead.
You can optionally replace Lunar Inspirationwith Rampant Ferocityfor more AoE, if you're able to get the mobs stacked well enough.
Use lorrgs to double check which add sets to use cooldowns on. Generally the first set of adds are not necessary to send your cooldowns on as your raid has lust running for this.
If you are the only Moonkin on your team, you can use Growlto taunt the boss before he uses the first Electromagnetic Sorting of the fight so you are not eligible to get picked for ball on the harder sets of the fight until the very end when the boss has cycled through every player.
You should cap on AP before the boss is about to use Electromagnetic Sorting and start casting Starfalla few seconds before the boss starts casting and use your cooldowns as he begins casting and keep casting Starfall.
Your Starfall will rip aggro on the Junkyard Hyena's that spawn around the room. Be careful of your positioning here. Try to be close to a tank that can take the threat from you. Consider using Ursol's Vortexor ask for an external if you're in danger.
Make sure to prioritize damaging Territorial Bombshells. These are the highest priority add, as running into them will wipe your raid.

At the end of each intermission, you can quickly re-enter melee range via Wild Charge.

Feral is generally a better spec for this fight as the heavy movement can feel rough for Moonkin and melee generally has an easier time on this boss.
If you get chosen to soak a far mine, run out quickly as the timing on some of the mine sets are very tight.
Consider getting a sound cue or countdown for when to run out and bait the drill mechanic.
Be wary of using Wild Charge as you can hit a mine on the conveyor belt, someone with another color or a drill on the ground.
