Healing CJN: Do I benefit from int, Pie and magic accuracy.?

All of this talk of pie is making me really quite hungry!

I'd love to know how CNJ that stack PIE 305+ have consistently higher heals than a CNJ stacking MND. Not to mention the bigger mana pool. I'd also like to know why the only piece of gear i can find that has +healing potency on it is from a hooded piece, limiting your ability to wear a head piece as well. Then the only materia I can find that again increases healing potency is a head equip. SE, you clearly dont want us stacking healing potency. Why not?

CON stacking PIE over MND do not have higher heals, do not have higher heal crits, and do not have consistantly higher heals.
Now they will have higher MP pool. Because PIE raises MP pool and MND does not. My previous post with the link to the dev post told you that much, as well as gave a link to the dev post stating so.
