Actually......you can......really easy.....
Its called Convert. With the right build (meaning getting back 6 mp per tick refresh outside of abyssea) you can recover every bit of mp you used in a fight, and while maintaining that 6 mp per tick refresh, can ride out the 10 minutes using the same avatar without even blinking an eye.
Also, in case you do need mp again, there is elemental siphon for those who can't get +6 Refresh.
And inside Abyssea? You wouldn't run out of mp at all.
MP is not the issue here. It is Dallas's claim that he can out damage everyone that is the issue. Don't take it personally Al, it is not you that they are attacking, it is Dallas.
