If they reduce MP costs, or allow us more means to regain MP back they will reduce the damage the nukes do to balance it out. Essentially we will be hitting more buttons to do the same DPS. Spamming.

When I wanna manage cooldowns and spam skills I go on ARC. THM has it's own flavor.

Now, I'm saying the above assuming you all understand that you cannot reduce MP costs, even as part of combos, and expect the same damage output as now. You all understand that, right?
Like i said i know how to manage my mp but i will say it again when you have to move managing mp for long fights are retarded. When doing the moogle fight as THM in the second phase the class is useless cause you have to keep running from stuff.
