Phantoms

Mille PDR hyper still works for all your other skills, at least in EMS.

That only works for that skill and you won't use it for almost any boss unless you are fighting mobs with it like at Empress especially when you have to stop for DR. The formula for phantom's pdr isn't changed when you add SP into mille's reinforce unless you really think you do awesome damage with it. The 20% doesn't make up for the lack of burst power behind other skills you could steal from adventurer jobs. They really need to at least double Mille before it becomes solidly useful (that's why people don't even use Final cut usually as well).
