Any type of melee zerg, tbh. Melee need at least 1050 accuracy before buffs/food to hit it even with Bolster'd Torpor/Precision.
The 2 winning setups I used were:
SAM DRG GEO GEO GEO WHM.
GEO1 for BoG-Vex and Attunement. GEO2 for BoG-Precision and Fury. GEO3 for Bolster Torpor+Frailty. We'd cycle Bolster and reset when all 3 were used.
We had 1 of the GEOs change to COR and do rolls pre-fight and change back to GEO and use the UC warp for a fast way back. Could do this with a BRD too if you had it.
Any 2 DD would work, really, as long as they are making either light or darkness and are very well geared.
or
SAM GEO GEO GEO GEO WHM
Same setup as above, but SAM(me) was making 4step light as sole DD source. When white would proc(seemingly random based on certain amount of damage dealt to it), the second light would do anywhere between 50-99K damage.
In a nutshell, as long as the DD(s) are buffed high enough to the point where they can hit it and pdif isn't floored, the fight is fairly straightforward and easy. The hardest part is getting that many buffers.
