The IDC chain is bad for nails. Nails should not be surviving long enough for the CT DoT to have any meaningful impact if you use it on the nail being attacked. In addition, the pierce debuff is basically in the same situation unless your entire group is DRG+BRD. By the time you get the second GCD off, the nail should be down to 40-60% hp.

This strategy with decent dps generally allows us to kill all the nails (even the big one) without using limit break, and is much easier for the healers to manage because they're dying at the same pace.
We use this approach to sell Ifrit with 3 DPS. The nails should die at a consistent pace regardless, but that is a skillcheck for your group.
