Tanks that think they are DPS, just stop...

[Chrono_Rising]

And if the tank gets hit with a few unlucky crits in a row? What then? Boiling it down to "lol git gud" is a stupid dismissal to act like a glorified DPS. Your first priority should be, as a tank, to hold aggro and mitigate damage, which is what the accessories do by giving you more eHP. The idea that we have to forego the accessories for our item level to get accessories from the last expansion because "hurrdurr its more dps" is not what I signed up for as a paladin.

If this is an issue then you don't have enough HP for the strategy you are using. See rule 1. However, I strongly expect 270 slaying to be patched out in 10 days and so this issue will likely be settled or pointless by then.

Honestly I don't like having to make this type of adjustment, more damage or vit, but as long as it exists it is a massive gain for the group. I hope SE just makes the sensible decision and puts some strength on fending or fixes the damage calculation or fixes tenacity to scale better.
