It's just the fact that VIT and Tenacity are very very unrewarding. Tenacity is awful and does nothing, and STR gear thankfully does not have that stat. VIT is more HP sure, but once you have enough HP to survive everything with some room to spare, any extra VIT you build just feels wasted. If it gave a little mitigation in conjunction with the HP increase or something like that, then maybe... Until then I'll just take my higher damage numbers, at least they feel like they do something.
