I've heard of this add grouping on either side of the boss, right on the edge of his hitbox so they don't link. With the changes to SMN MP I'm curious if anyone has tried pushing crazy DPS on SMN using this.
The way I invision it.
Ifrit Opener with Rouse/Spur Enkindle
SC Garuda after buffs wear off.
RS +Pot Contagion just prior to adds. (BV Foes while applying dots)
Shadow Flare inside bosses hitbox to hopefully get adds. Bane from boss. Stand inside boss M2 +Blizz II spam.
SC Ifrit after adds.
2nd set of adds. RS Dots +Foes prior to adds Contagion. SF M2. Rouse/Spur Enkindle off Boss to hit all adds +Lvl 2 LB
SC Ifrit and finish fight.

Alternatively you may want to use Rouse/Spur Enkindle with Garuda on the first set of adds due to Enkindle not being up again for the 2nd set due to fast kills. This combined with Aerial Slash will be more damage than using Ifrit. (Instead of opening with it on Ifrit)
