That said, it wouldn't be true MP management. Think of it like FoF having the MP bar ticking down instead of having a traditional buff timer ticking down (except it only ticks down when you use a GCD action). FoW would be used directly after and would refill the MP bar (I accidentally deleted that part) through normal gameplay in lieu of having a recast timer for the FoF buff - it would fill slightly faster with Tornado Kick usage when it's learned in lieu of having a traditional recast timer reduction trait. It would sort of echo PLD's MP management in a world where they only had 1 spell that used MP. More symbolic than anything and requiring about as much thought as MCH's Queen usage.
If you want MNK to have a resource gauge to spend, then Chakra should be made more robust. It has no need to use MP and that's exactly why it stopped using it. MNK has so little identity as it is, let's not blur it even more by making it a magic job.
