Definitely not criticizing you for doing a Wind magian. On my to-do list. Holding out incase SE caves and gives out a Prism I staff that you have to trade all Magian I staves in for (similarly a Prism II or III staff, but I don't care about those).
As for the INT/MND bonus, it might be nice for the odd cure you have to cast on Dark Arts. That and/or the extra 20INT oomph (supposing full merits) to tack on to a powerful Helix when you need it to count.
