If we want to enfeeble better and actually have it mean anything in endgame, aoe debuffs of current spells, and a debuff limiting aoe abilities to single target are the only way to go. I know a lot of people think aoe debuffs are useless and that "enfeebling only works on fodder" but thats exactly the point. In situations where fodder must be killed at extended durration between larger targets, debuffing a whole squad with para/blind/slow and making them hit like little girls, while applying Dia III-ga would simply make the killing of these safer, and require less effort for healers. From there the focusing enfeeble would be best utilized on said bosses, but outside of these there is little that would make rdm relevent via enfeebling outside of a debuff that occ. caused mobs to recieve doub./trip./quad. damage similar to aftermath.
