I'm not sure if anyone else has noticed a significant change in MP economy since the last patch hit but I know that in my personal experience MP flows a lot less freely and I see myself constantly battling against running bone dry while trying to be constantly casting. I never even thought about using Break for mp free dps before but its definitely appealing now. It seems like an intentional adjustment based on the way Piety seems a bit more scare across the current Healer Gear. If so it is a buff to White Mage and nerf to Scholar. For Scholars using Energy Drain for MP is a direct cost to any other healing skill that could have been used instead and managing Aetherflow effectively for shields and heals and cutting back on dps to sustain mp means that White Mage can push their dps a lot harder than Astro or Scholar. I may be imagining it but simply changing mp economy could be the key to pushing WHM forward.
