Your Classes and what you do.

[Arcell]

Every class has MP and most of the time we wont use it, unless your like me with spells, on the flipside it could've been 250 TP for every 10 mp we use

Try adding more Dex? or Dex+ stuff? works wonders.

Dex will only really help with evade and it's currently debatable how much it actually helps considering most stats don't work the way they should.

The point isn't that most people don't use MP, the point is that Pugilists NEED MP for some of their basic attacks and have no way of regenerating it on our own. If you run out of MP you lose two of your basic attacks for the rest of the fight.
