Snag a DD friend as a 6th and do the mentioned /Dnc bit and you'll be rocking them pretty good. Those pugils and crabs only have about 14-15kish HP. Did something similar earlier today actually, though it was Sam, Drk, Geo, Ulmia, Joachim, and Koru. I didn't keep an accurate tally, but with a 50% CP cape, 2x charges of Capacity Ring and about 70ish minutes of grinding, I pulled in 4 JPs.
