Elemental Ethers

[Karleguarth]

So I performed a test to see what are the relationship between my Elemental Affinity and the elemental counterparts of the ether.
Result I got is frustrating...

First, my affinity points:
Fire, ICE: 114
Wind: 35

I used fire ether when I start the test, 40mp
I was thinking, perhaps the mp gain is related to strength and weakness of elementals..
So I tried ice ether, as it beats wind, my worst affinity point, and it gives me 40mp
Lastly, I used a wind ether, hoping it works in a reverse way that I got the most mp gain by having a low point invested... and 40mp as well.

Any thoughts?
If anyone is able to get more than 40mp with the elemental ethers..
please share what you know
Thank you

Ether gives 50 mp, elemental ether give 40 mp. Potions and ethers in this game is worse than any FF game before. Also, COOLDOWN??? wtf!
