Possible Cure/Non Interrupt exploit?

[Dashuto]

MP regens pretty quickly outside of battle. The MP consumption isn't really an issue. Say they burn through all of their MP on an attack. Within what... fifteen seconds? they're full again.

Suppose they /aren't/ out of battle 90% of the time, which is the case. I know you have only my word to go on here, but please entertain the thought.
