It's there mainly because warrior general gives a strength boost. Heck, Strength could be boosted to provide 1.5 matk for the purposes of the skills if that would make statting str make more sense.
I agree, Borella, that P/W should have been given the chain gear elite. It's almost like RW decided on it & then decided to piss off pretty much every P/W in existence.
Even at 1.5 ma and the str passive I still don't think that beats the 2 ma/int ratio. At cap the str passive is 9.3%. So:
100 str = 109.3 str x 1.5 ma = 163.95 ma
100 int = 100 int x 2 ma = 200 ma
There's no real way that you win statting str if they changed the skills to be based off of matk vs mdef.
EVEN IF they changed str to give 2 ma for P/W only, it's far easier to find int/ma than it is to find str/ma. There's no orange str/ma so I guarantee int/ma would still come out on top even with the str passive.
Give p/w the d/w elite, boom fixed.
