I think I sorta get what you're trying to point out, Ein. But how is forcing a new play style via new stat any different from forcing a new play style via mechanics? I mean, like others have said, if they increase incoming damage to the point where you need vit over str, that's still a dps nerf? So if the change the damage formula instead (let's say they do nerf damage), I mean that's still the same result either way, more HP less dps.

I think, though, it has less to do with dps and more to do with making gear relevant. They are overhauling materia melding, crafted items will be more powerful than they've been able to be in the past since we'll be able to meld raid gear, and I think "fixing" tank damage is part of the plan to smooth out gear progression as we move forward. Because we need to know what a tank is going to bring to a raid. Is he going to do 1000 dps, 500 dps, 754 dps? We need to be able to plan/make expectations and having vastly different gearing options doesn't make it any easier.
