My group is:
DRK/nin (stuns -aga)
SAM/nin
MNK/nin
THF/nin
WHM/sch
BRD/whm (main sleeper if needed, back-up healer)
I'm the WHM. Originally I used to go RDM/whm, but I found it a LOT easier as a WHM, but I think /sch is a must if you want a WHM over a RDM. Repose is great too, last a long time. I've been floor 100 for a couple months now.
