To me, it feels like MP doesn't matter any more. Now that lilies have been buffed, it's so hard to run out of MP on any healer, unless you completely forget about Lucid Dreaming for several minutes. And that's with every healer avoiding Piety like the plague. So what's the point of having MP at all? Just to make death even more punishing? To encourage newbie healers to stop spamming AoE heals when everyone is at full health?
Personally, I like it when I occasionally have to worry about MP. It can be an extra bit of complexity for the healing puzzle. I wonder what it would be like if oGCD heals cost MP.
I dunno, how do y'all feel about it? Should MP management be an important element of healer gameplay? Should it just be a niche optimization? Or is it boring/outdated and not worth the time to fix it?
