You keep bringing this up. It happens once a blue moon.

You keep blaming Tanks, how about instead of blaming the Tanks you blame the playerbase? The game has been gutted because people can't even press their basic combos. The player base is a casual playerbase and the content has been nerfed into the ground because the majority of players that play 14 aren't good at video games, they are here for the story. Yoshi literally has been nerfing content since ARR because players simply aren't good enough to do the most basic of tasks. They couldn't even access HW expansion back in the day thanks to the original Steps of Faith.

Yoshi has seen where his bread is buttered and unfortunately for us it's the casual market. It's why we will never see bosses randomly critting come back, it's why we will never have enrages in normal mode again and it's why we will never see anything remotely difficult in this game for story mode content. It doesn't make sense for business, and this is a business. No one was playing Tanks until Stormblood, so they gutted all the Tanks to bare bones rotations. Healers could not heal and would constantly let Tanks die so they gave healing to the Tanks for a more balanced game play so losing 1 role doesn't completely wipe the raid and to entice new players to try Tank without Tank anxiety. Turns out it worked quite well that they kept at it and it seen a huge boost in popularity. Funny how that works, they look at stats and it gets the results they want so they keep at it. Why would they do something that actively hurts their bottom line?

You might want your jobs to play a certain way, look at BRD and MCH players, I'm sure they would like to go back to HW and SB when their jobs were relevant. Personally I'd love Monk to go back to it's old ways, but no one played it so it had to change, I don't like the change but it's there because it's good for the health of the game. It's a casual game. You say it's bad design on the Tanks part but it's quite the opposite, it's great design. It boosted the number of players playing Tank, with more Tanks queues pop faster, with faster queues you have a smoother gaming experience. If the trade off is once in a blue moon a Tank will solo a fight because everyone else died then I'll take it. I absolutely do not want to go back to 40 minute DPS queues. Do you remember them? It was absolutely miserable playing as a DPS back then.
