Heavensward was the peak of combat design given the debuffs meaning anything, Tank stances and enmity being required, Accuracy requirements needing to be met. Stormblood was when they started to dumb everything down to what it is today.

So instead of jobs with identity and pierce meta comp we now have jobs that mostly feel the same and half of them are broken.

HW required Tank Swaps even in some normal raids, and there was definitely heal checks that needed to be met. As it is right now they have made the game way too easy.
