That is an incredibly bad way to go about this fight.
Our setup which was 4min wins (cause waiting on last 2 DRG repops)
PLD (or RUN) tank
WHM
GEO
BRD
WAR
DD COR (this guy needs a real savage blade set)
Buffs are
Marcato HM + VM + Lightening Carol x 2 + Barthundra + SAM's roll + Hunters Roll (COR wanted it) + Frailty + Fury
PLD runs in aggroes, pops sentinal and runs back to the corner were BRD sleeps them. At the same time everyone else is running to the middle where the GEO would of Dia II'd a DRG to pull it in. PLD "tanks" the pulled add as best but they are going to lose hate very soon.
Our SC was
Upheaval -> Savage Blade -> Upheaval
3/4 of the time the add was dead after the Savage Blade, if not the following Upheaval guaranteed their death.
Adds pulled are
DRG #1
DRG #2
MNK #1
MNK #2
DRG #3 (repop)
DRG #4 (repop)
Don't *** go /NIN and leave the WHM slept. Lightening Carol x2 + Barthundra is sufficient for the stun off the MNK's to have no effect 9/10 of the time. Allowing the heavy DD to use a real sub to kill them faster.
Super easy fight, finished in 4min from entry to exit.
