Or very simply go back to the tank damage calculation from before SB.

Also it doesn't help the fact that Tenacity is pure garbage, so I rather keep my slaying 270 accessories.
I had the opposite experience happen in PF Susano EX. Warrior had 40k HP and if he wasn't always completely topped off he would mostly likely die the next big hit. The big hit was coming in around 35k HP. This isn't a big deal the first part of the fight other than having to baby sit the tank, but would have been an issue on the last phase with all the other dmg going around. This was not a farm group (no clears) so healing requirement was greater due to gear and occasional missed mechanics. Never even had to stress this with other tanks with normal HP.
I have absolutely zero issues with threat tanking everything in the game currently in full vit gear. That said, when raid time comes and I trust my healers more, the ONLY thing that matters is having enough HP to survive the tank buster, period. Any additional dps you can squeeze out of losing whatever's left over just means that you're doing the fight faster and making things easier for everyone involved. Will they lock str accessories before the raid? Maybe. And I hope they do. But until then, str accessories will be mandatory for savage raiders unless the encounter has a mechanic that hits you for 60k through invuln
ANYTHING at this point that takes ANY LITTLE THING away from tanks, no matter what it is, is gonna get a big NO from me, on account of there being so few tanks already, and queue times being horrendously long and becoming longer, that any nerf is going to hurt the entire playerbase much more than it benefits a few narrow-minded traditionalists who rather see tanks be blocks of stone swaffling you with a foam bat.
