I think them keeping STR in our gear is intentional. By calculating AP with VIT but not phasing out STR entirely, they're actually nerfing our damage, as only one part of that whole can be on our right side gear, melds notwithstanding. Ironically, keeping STR in the equation is directly correlated with a potential nerf, which is probably happening to keep us from having the current HP/AP of both full slaying/fending builds simultaneously. If they remove STR entirely, I think they'll be making both HP and AP scale at about a 70-80% ratio with VIT. So it'll be like we've got pentamelds on all the time, which i would have zero issues with.
