Unless the -enmity trait can break the -50% enmity cap, it won't do much for any of the 3 jobs in fundamentally changing how they play. If MND played a greater role for Cure 1-4, sure, but once you get past Cure Potency and -Enmity, the only real choice left is lolConserve MP. Good luck convincing mages with already clogged inventories to whip up a set for that. :x
