Full STR WAR is nothing to write off.

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.

The highest reasonable minimum heals for that yes. I agree with your numbers here, i disagree about requiring insane STR gearing.

Gryphonskin with 45 strength and 45 dex adds about 1% total mitigation. If you went full STR and gained 1% mitigation out of it, you'd be behind for all cases less than 1000 incoming DPS due to the difference in passive regeneration alone.

Everyone always forgets passive regen. I don't consider the mitigation gain to be the main reason for taking the STR though, the main reason is Inner Beast. That and making easy-mode threat even easier, allowing me to use Storm's Path more often.
