Well if it means anything, +3 ethers allow for what, 80 mp back, and then there are the fire/earth/water ethers or whatever and those I think MIGHT have an impact on what you put your stats into elemental-wise.

But as they are, yes they need a huge boost and if they don't get one then I guess we're going to have to wait for when the stat fixes come. If they're fixed to the point where you need most of them in MND, then eff-all. I still wouldn't do it. Lower MP is worth having stats put into VIT.
Especially if it means living longer.
