I think it's great that we have a "Cure Potency" trial staff to rival the Light Staff, as well as the other elemental affinity attributes, but I've been wondering why we haven't seen a trial staff to rival the Dark Staff's "MP Recovered while healing" stat, or "hMP."
Maybe I'm alone on this, but I still do plenty of things outside of Abyssea and would love the same kind of jump to hMP that I can get with my Cure Potency staff. We also have trial weapons (not just staves) with stats similar to the ones on the elemental staves, so I don't understand why we've skipped out on hMP when everything else related to the elemental staves is accounted for.
