RDM's Patch Notes?

[Nyvara]

A fundamental problem with the previous MP values is that Red Mage is punished in dps heavily by the existence of verraise. Before they lowered the costs, Red Mage could hardly use verraise without bottoming out their MP. You could only use it 2-3 times in an entire fight before running into crippling MP issues.

This. We went from being rez mages to reznot mages.

People did the math and even executing your normal rotation perfectly and using LD on cooldown you would have max 15 minutes of fight before running dry. Each Raise was costing 4 minutes on that clock and if you'd die you couldn't count on LD to help you since even on CD it wasn't enough. Also, caster gear tends to have SkS on it would have compound the problem sooner or latter. RDM had MP issues. period. and that's why the potencies have been adjusted.

LD is meant as a tool to help recover if you need to use VerRaises or VerCures or if you're getting raised yourself. It hasn't meant to be a mandatory part of the rotation

That 15 min thing is something I ran into that's when I knew RDM was in Deep trouble. I'm glad to see the mana reductions!
