I think the numbers are:
(ifrit > 20%) + > 2,500tp = DS2
(ifrit > 20%) + < 2,500tp = chaosthrust
(ifrit < 20%) = chaosthrust
and buffs should be prioritized for DS2 pre <20%
consistently our best DPS'ers are the ones who use chaosthrust more then the others, usually I say our good DPS'ers do 25-30 with harpoon and 22+ w/o harpoon.
