If you note my parses are typically higher than the players below me or I’m running with people who are under geared. Both of those make a huge impact. If you take an equal tank and dps in both gear and skill than the dps will always beat the tank except on high count pulls with dps that have aoe caps such as the first pull in AA.
In the first instance this was a pug with a insane healer (well over 3K) and they did a 98% for the key while I was doing a 78% all of the dps did lower with one parsing a 8% for the key. Which means you are comparing high skill versus lower skilled players and even there I’m what 2/3 of the dps as a 34% parse.
In the second case Cruorosa is a new player and she is still learning the correct fury rotation. In addition she has never run M+ prior to that season and we were getting her more confident with mechanics. While sub has done some M+ it was our first run with him and hes good for mid keys but probably needs some work to push into higher keys.
In both of these however you can look at the dps who are pulling closer to what they should in those keys and you will see I do about half the damage. And in many keys you didn’t list you will see that I do less than half particularly if I play with Imp on his pally or priest.

Its necessary for there to be difference in the way tanks handle damage. Self healing allows a reactive style while mitigation allows for a proactive style. Each tank allows for different amounts of these. Its not a hole or flaw but purposeful design that is good.
A tank with self sustain has existed since at least wrath and has never been a problem. However what is the role of a healer to heal damage when people need it and to deal damage when they don’t. Which they have been doing.
The main goal of the dps is to do damage, they do this job. In addition they are given a ton of tools to help mitigate. More than at any other time in the game. Should they be able to do half the mitigation probably not because they are not tasked with mitigating auto attacks which is the primary source of damage.
In all honesty though I don’t even get the point of your post. A tank has two things they need to do to fuffil thier role. Establish threat which requires damage (if you don’t want tanks to do damage thats fine but we still need threat somehow,) we than need to mitigate the damage done. They are taking away that second tool, we don’t have nearly enough tools to survive the tank busters in live.
Is there perhaps a good middle ground sure but I’m not talking about design philosophy but rather what is happening on beta right now and tanks have been hit hard enough where in some cases they simply can not even pull the boss without getting one shot. Obviously that is not good design.
That and despite stated intentions we are already seeing kiting happening on the beta.
