Use your Infernal. Doomguard has no place here.
For sustained AoE, you want to take Harvest Life. Set up your AoE by using your Wild Imps then put Corruption on everything. Once Corruption is applied, you should be nearly full on Demonic Fury. At this point, pop Dark Soul, Metamorphosis, Immolation Aura, Wrathstorm, and Fel Ray. Fel Ray will refresh Corruption on all targets it hits. After you do that once, use Harvest Life to generate as much Demonic Fury as possible only stopping to refresh Corruption with Fel Ray and to refresh Immolation Aura. Using Soul Harvest after you run out of Demonic Fury will restore your Demonic Fury at a very rapid pace. Do this until you're down to 4 or less targets.
At 4 or less, keep Corruption and Doom up on every single one while using Hellfire and Wrathstorm off CD. Pop Meta when possible and use your Imps to power your Demonic Fury gains.
First of all, Harvest Life costs Demonic Fury while in Metapmorphasis, and it has negligible damage compared to better uses of your fury.
Secondly, your damage will mostly consist of DoT spells over the course of this fight. It's best to keep Corruption and Doom on every single target right from the beginning, and you should pretty much never be using single-target spells while more than 4 adds are alive (and one group of them isn't too high on health, obviously).
Third, you should be using this macro:
/use [noform:1] Metamorphasis
/cancelaura [form:1] Metamorphasis
This'll give you a button that will drop you out of Meta form if you press it again at any time while in Meta form. Much better than having a 10-second wait time on the default stance button!
The trick here is to try and keep floating between 400 and 900 Demonic Fury throughout the encounter. The best way to get this started is something like this.
-At the beginning of the fight, prepot and use your Wild Imps and your Wrathguard/Felguard's whirlwind when he is in range of all targets.
-Put Corruption on every single kill target, and drop a Hand of Gul'dan. (Save 1 charge of this at all times, but never sit on 2 charges)
-When you are around 700 DF, swap to Meta form, use Dark Soul/any on-use trinkets and apply Doom to everything. You probably won't have enough fury to do this AND channel Immo Aura, so don't bother. Before leaving Meta form, drop 2 Chaos Waves, and stay in that form and cast a Void Ray until both waves land.
-When your CW's land, swap back to caster form and proceed to Harvest Life until you are around 900 fury. If you accidentally let Corruption fall off of something, now is a good time to re-apply.
-Pop Meta at 900 fury, and channel Immo Aura while weaving Void Rays and Touch of Chaos until you are back to about 400 fury. Use any Chaos Waves you get in the meantime, but make sure you don't cast them when you are too low of fury, or when you're about to leave Meta form.
You'll pretty much be repeating the last two steps ad infinitum. The reason I never use Hand of Gul'dan in this fight is simple: I'm not doing much single-target casting, and Harvest Life/Corruption are generating more fury than I can spend, more often than not. Chaos Wave, however, does an insane amount of damage on this fight, so utilize it.
And for God's sake, don't use Mannoroth's Fury on this fight. You'd be amazed how easy it is to clip a CC'd target.
EDIT: And yes, use an Infernal for this. But do NOT drop it on top of the mob pack, or you'll make Mel'jorak clear all CC on his entire team. Drop him away from everyone, and let his little green ass walk over to 'em.
