Fiddling with equipment stats, it seems that max STR on a WAR is 466 with 290 DTR after food. This is all ilvl90 gear. Should get +2% STR from party bonus as well, which is 475. Valk's formula predicts 1.393 damage per potency, less than what is needed. However, any discrepancy in Valk's heuristic could make it possible. Kind of academic, though. Maximum non-crit, non-buffed IB heal from Valk's formula would be 1672. That's your design limit. Realistically, you can't exceed 1500 without severely clipping your HP. You'd lose 50 STR -- 30 from bonus points, 20 from going to ilvl70 Gryphonskin with 9 STR per piece instead of 13. You'd also gain 75 VIT, or around 1400 eHP. Would put you at 487 VIT before party and food, which is about 7822 HP after Defiance. With party bonus and food, should be 8202 HP -- good enough. Anywho, that's 126.4773 damage per 100 potency, or about 1518 healed by your average IB with Maim and SE up. That is all ilvl90 armor and weapon with ilvl70 melded accessories.
