XIV EW Job-Gameplay is Terrible... Why?

[Valence]

I'd argue it was absolutely already a creeping problem in Shadowbringers, but limited almost entirely to tanks (really only Warrior and Dark Knight), healers and the phys ranged that weren't dancer.
Endwalker just followed ShB's awful design philosophy even further and amplified it tenfold by making everything some kind of divisor for 120 seconds.

Agreed, the biggest changes happened in SHB, not in EW. EW just compounded on the issue by doubling down on the design. People are only waking up now, but it's been bad for more than 5 years already.
