Full STR WAR is nothing to write off.

That's the thing. That 1,300 damage hit on Inner Beast just healed the guy who did it for 3,900hp. About half his health. That is why STR gearing is a great idea on WAR and only an OK idea for a PLD... maybe... if you have enough HP.

Breaking 1200 requires insane DPS gearing and STR pot. The highest reasonable average shot heals for 1500 or so with Maim and Storm's Eye up (1.25 damage per potency). You get about 41% more out of Berserk and 50% on crit.

1200 hit => 3600 heal
500 hit => 1500 heal

Assuming you geared Warrior like you would a normal tank
369 STR (50 less than your current) and 534 VIT (50 more than your current). Which is closer to 420 hit with just Maim and SE.

I've already tested this amount so it's much more reasonable than how you chose to gear yourself.

369 STR (50 less than your current) and 534 VIT (50 more than your current). Which is closer to 420 hit with just Maim and SE.

If you wear Gryphonskin accessories and allocate VIT, you will have 410 strength before party bonus. Beyond that is going to be rehash of the Gryphonskin vs. Allagan debate we've all seen 4000 times. Your hit is with 352 strength and an ilvl80 Bravura. You will get the remainder of the 500 damage from the elements I have pointed out.
