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

Yeah I'm getting really sick of so many people equating "needing to stack vit" with "being lazy". There's no correlation. Tanks gear their health according to the maximum size of hits they expect to take in an encounter, or according to what "free" health they get on their gear. If all fending accessories had strength on too you'd see tanks with closer to 20k hp in Alex Savage, sure, but they'd still be using the same rotations and cooldown use.

How much Vit a tank needs is of no relevance to how lazy they are. The -weaker-a boss hits, the less vit they need. If they make all tanks use nothing but fending accessories you can bet they'll increase the overall damage coming at them. The tank buster in A1S hits for 25,000 damage, which means you can easily survive it with cooldowns and a tank stance with around 16k base health. If the tank buster hit for 35,000 damage then tanks would be stacking Fending gear and you'd still need an even more perfect top-off of health + shielding to survive.

Stop with the ignorant "needing vit = lazy" arguments please, tanks gear as appropriate to the encounter and play the same regardless of their base stats.

And as for " letting healers carry all the weight." - this is precisely what the current Meta enforces with the need for tanks to tank in DPS stance so frequently to hit the dps checks. A conscious decision to make yourself harder to heal in order to push out more DPS. The amount of incoming damage in an encounter is a joint effort between the mitigation of a tank and the heal output of a healer, and in the current meta tanks are pushing as much weight onto their healers as humanly possible by gearing to be as squishy as they can get away with to maximise dps output and pushing the onus of surviving onto the healer team.
