As a whm I think you're expected to be able to swiftcast raise. Eye for an eye is very valuable, but others can and should have it.

I'm 50 in all crafts and honestly don't think it's that helpful. Materia slots aren't on as much gear as you might expect, and it's not worthwhile to swap out differnt combinations like good old FFVII - you just meld it once and forget it.
