What they mean by "change the damage calculations of tanks"?

[Hayward]

If they're changing it so we scale off VIT instead of STR I really hope we're gonna get compensated for all the eso we spent on slaying accessories.. I have like maybe 3 fending accessories at or above i200, I'd hate to be using STR accs when STR is useless to us, I'd feel like a drg running around in aiming accessories >_<

Sorry, but that's on you. No one put a gun to your head and made you pick out the wrong accessories (unless, of course, you have MNK and/or DRG at 60).

If this means VIT will affect damage output (and hopefully enmity generation and parrying effect), I'm all about it. All that would be left is to catch some tanks up on tanking fundamentals.
