I...kind of agree, especially since full vit tanks are completely pointless and not required in later parts of the game because all that HP serves nothing in dungeons (enemies don't hit that hard to begin with), and in raids tanks HAVE to do damage too and having a full VIT tank is usually not viable. Besides, most of the BiS accessories are the penta-melded crafted accessories (which not everyone can obtain: I have to stick with str accessories).
In short, full VIT (which means ignoring STR) gear is not worth it, especially in a game where damage is the only viable option, even on tanks AND healers!

Apparently they are modifying VIT to give damage on tanks in the future...but I don't see a problem on giving tanks both STR and VIT: with the exception of the warrior, most tanks do okay damage overalll and if it's an issue just remove those damage buff like Maim on Warrior, Darkside on DRK and F&F on paladin. They'll have high STR, but still 20% less damage with their tanking stance and if they want to dps, just toggle it off and go damage!
