Manashift has a 120s cooldown now instead of original 150s cooldown. About 3000 MP transferred to a single player at Lv.70.

Refresh has a 180s cooldown. About 6000 MP recovered per party member at Lv.70.

Manashift shares the same 120s cooldown as Lucid Dreaming. SMN/RDM can use them together to recover the MP to make it basically free. However, BLM has more MP complications with Lucid Dreaming and Manashift. Manashift is not as good as Refresh, but BRD/MCH need a reason to be in parties too.

In God Kefka, some healers have only 16,000 MP because everyone on Reddit and official forums keep saying Piety is useless. Inevitably, they run completely empty on MP. Piety is not useless, since it provides economy for actions (damage and GCD efficient Cure II's) and buffer for mistakes (costly Raises). If healers are running out of MP, they need to get more Piety. If you play AST, you need more MP than other healers at the moment.
