Well in all fairness.....just get more piety gear if your struggling with MP in game

White mage have thin air, even know it is getting nerfed in endwalker, it still save mp by a lot, u can get 1 free cure lll off or a free Raise

The only time ANY healer will have mp problems is when they are hard casting raises due to player mistakes , which personally i would turn raise into a 20-30sec cd with no mp cost

At low level there isnt really MP issues , but i will say this, due to lack of ogcds you play very differently as a healer

For example whm whilst holyspam will use lucid and do. Holy > holy > cure > holy >cure and if u get "free cure ll" you use that instead

I know alot of people say the "free cure sucks" and they kinda right at "high end" but low end where you dont have alot of ogcds its a god sent
