No TY. It would most likely be like way more interesting to design individual depth through how they self-sustain/recover and their trinary theme. GNB could be technical, it seems to want to be a faster high-speed assault combat style, feels and looks aggressive, and makes use of a pneumatic sword and charged cartridges, which could add a lot of impact and flavor into it's design. DRK could traditionally has a lot of risks (blood for blood is like literally what DRK is in most versions) which attracts certain players, and literally steals MP and HP in several iterations. PLD is civilized (will injure or trick/fight dirty), sturdy, self-sufficient, and is mostly ok. War could definitely be a strong-self-regen-tnk if they go more into the berserker stuff with a good momentum and aggressive high-adrenaline style. There is literally a lot that they could expand upon that would be more interesting than more generic damage-reduction buffs
