The change to the stat system causes a few oddities in builds. PWR is essentially a meaningless stat as far as roleplay and characterization goes. It doesn't correspond to just physical strength or to mental acuity either. It seems to act as just a damage stat, and one that nearly everyone (except for DEX based damage classes and Red Mages with Charismagic) is forced to pump to remain effective. For ease of discussion I'm going to use the concept of generally mage classes (Black Mage, Time Mage, etc) and generally warrior classes (Fighter, Dragoon, etc) The problem is that mages do the same amount of damage as warriors with weapons, and it is very easy to multiclass from a mage class to a warrior class or vice versa without making any sacrifice in damage output between different methods of attack. It is conceptually strange that mages would actually do worse with their given weapon category (Arcane) because all of their spells work off of PWR and so they would probably be pumping that stat more for the damage output and equipping a PWR based weapon as well.

I understand the intention was to make it easier to multiclass, but perhaps someone who's building for that should be forced to plan ahead with a balanced build instead of making it so easy to switch between mage and warrior.

Additionally, this is mixing in a purely combat/mechanics based stat into the same pool of points as stats that have characterization and roleplay meaning, like MND or DEX, which makes tuning stats to fit character concepts well frustrating. Everyone wants to remain effective and relevant in battle, so PWR is going to be pumped no matter what, but this comes at the detriment of the characterization-focused stats. You can see this best in the fact that every non-skill roll will end up either force or finesse, which essentially abstracts down charisma, intelligence and dexterity all into one stat, and physical strength, constitution or health, and some abstract measure of magical power (represented in PWR stat as well?) into another roll. It feels homogenized.
