Hi Noctis,
Definitely. It's something that a few people have wondered about:
* The Quantity of "Valid Stats" that Paladin has to worry about (compared to Warrior or other classes).
As you brought up, there's STR and MND, and VIT. And if SE ever fixes DEX (for Block Rate, updating Block Formula), then that's one other Stat to worry about. Whereas other Jobs usually just need to worry about 2 Primary Stats, and in Warrior's case it's just STR and VIT (and VIT inherently adds HP and Defense).
There are some fundamental flaws with the way SE has designed the job overall IMO.
