why exactly would you want str and int at all ? str adds 1 armor a similar level affix has about 3-4 times as much armor
intelligence adds 0.1 resistance ; but an similar tier + all resistance has about 4 times as much as well.
that being said you should not look for Intelligence or Strength at all ; if you feel squsishy stick with resistance or armor - affixes
Hmm I can tell you if you find gear with +armour or resists on they are better then STR & INT for raising these values BTW your better off taking the One with everything and stacking say fire resist to get your resist stacks up. As things stand getting the "one with everything" passive will boost all your resists to 325, for 52% damage resist.
As things stand your best things to increase in terms of EHP gain are VIT at 123 EHP per point Resist at 336 per point and DEX at 53 per point and the rest are ~30 per point (with out the one with everything passive).
With one with everything, VIT becomes 132 per point, then DEX at 58 per point and then any resist at 336 per point and the rest are at 33 per point.
You can use this to see what your EHP boost are depending on your stat changes https://docs.google.com/spreadsheet/...XMyaFI2Y1VWNFE
Put in your current stats and go to page 2 and the per point will tell you what you will gain in EHPs for 1 more point of that stat. Note the resist all is assuming you are taking all 6 damage types.
