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

[Alahra]

I do expect there to be some bloat in numbers, I just prefer a seperation in the stats that determine my damage output and my health.

I don't disagree here--my general preferred solution is a split between STR and VIT in some way, with just enough of VIT contributing to damage to make Fending the preferred accessory choice. This will allow the developers to better predict both tank DPS and tank health pools when designing future content, which should (hopefully) result in better encounter design.

I think full VIT for attack power is the wrong way to go for a number of reasons, but it wouldn't really change the HP totals the developers expect, since they have always likely assumed full Fending accessories in the first place, since that's the gear tanks have Need privilege on.
