It must be a sketch instead of calculation result I assume. I also assume x is boss' DPS or tank's max-allowed unmitigated DTPS, and y is probability distribution (which should be normalized). So the death probability is the overlapped area. If this is correct, it didn't support your point that tank meta is useless, and I don't think how you analyse the change of distribution is correct. Tank meta will first shift the whole distribution to the right by a little bit (stam increase), which obviously decrease overlapped area. Then also bump up the right hand of the DTPS peak and makes it asymmetric (reduction proc). Since distribution should be normalized, the overlapped area decrease too. If we want to look at the effect from this graph, ofc it will increase your surviving probability. And about how much it will boost you, it's a very subjective thing. I don't doubt that for top players like you mentioned, who has top gears and skills, in this graph, the boss DPS and tank DTPS peaks are far away separated (death chance is already low enough), then the tank meta boost is totally ignorable. But for a mid-class player, whose gears are not that good, raid is not that perfect either, these 2 peaks could be very close (death chance is high) and tank meta in this case could make a difference.

Unfortunately my main isn't bear either, and I haven't done an actually simulation, so I can't tell how much it can actually affect a bear. But my idea is, if possible, get 2 helms and gem differently, and swap depends on fight, at least this is what I do to my DK. It's only 5 primal diamond after all. For a fully heroic geared tank, you probably don't need tank meta on H Lei Shen. But for, say, an ilvl 510 tanking H Tortos bats, then why not?
