Did somebody take your sweet roll this morning dark? I'm sorry.

If you are running out of mp quickly in longer fights such as Ifrit
you are either

a) doing something wrong
b) getting to many resists (go back to point a)
c) pulled the short straw and got stuck in the melee bitch seat on a thm burn

Yea mp "management" Is a ten ton iron bitch with thm. In that you do not so much manage it as you apply a tourniquet to stop the hemorrhage. But its possible and possible to do it while dealing consistent damage.
