I would like to see the main stats changed a bit. WAR's main starts are STR and VIT, I think? Thats why they have huge HP pools.

MNK should have VIT as the second stat. VIT gives more HP and MNK has had VIT and more HP as a trait in the past.

And PLD needs a bit of VIT as a main stat for HP and def.

So maybe change WAR's main stats to STR and INT or something. MNK can have STR and VIT. PLD VIT and some STR and MND.
