maximize damage

[mof]

I personally would say though that the advantage of SPR (extra MDEF and SP) is important, if only because I burn through SP like a bamboo forest on fire. (And I have no idea how to properly optimise it.)

Hehe I couldn't agree more. But I think here's the optimization part - use me as an example:

I noticed that when I solo, I tend to lose more hp than sp, which makes sense... I don't have enhanced armour and I take some damage. Straight forward enough.
Conversely, I use a lot more sp than hp when I'm in a party with a fighter or a cleric (don't need to burn sp as much).

So you can choose anywhere on the spectrum to suit how you play. My preference is going with more sp - skill spamming = more fun!
