For some reason I find myself having to Raise people more often (and surprisingly we manage to pull through and avoid a wipe) so the thought crossed my mind that with Aetherflow being a flat % regen it might scale better than Det (probably not Crit though) Essentially my stats would be something like 44 crit 31 piety. But I'm not actually sure how much extra MP that would give me...

Outside of Raises I don't really run out of MP except for fights like Titan (high movement lots of Ruin IIs), Mog/Ifrit Ex (lots to dot) etc. Hmm, so it's not super rare but it is uncommon. I actually dislike asking BRDs to sing because of the DPS decrease and the off-chances a healer bites it and needs a boost after being rezzed, but I know that is part of their toolkit.

I suppose it's not worth it. Sigh. I wish this game were more open to alternative builds. Customizable stats and everyone is running around with the same thing still >_<
