Well because it's the players complaining that apparently struggle to unite two brain cells to work in conjunction with each other that causes alot of classic instances to be dumbed down to rather insulting levels and then the devs keep this flow.
Devs should have never listened as much as they did to the whiners. It's part of this reason alot of this game has suffered over time. And its not only casual players but raiders too.
Raiders complained about difficulties lining up raid buffs and boom everything is two minute windows. Raiders also complained about hp pushes and randomize mechs which gave us a cool fight like T7 savage (or the regular version too) and instead we moved to predictable dances that cycle similar mechanics every fight for now like 7 years. Raiders are now doing the same with Picto in FRU. Trying to rob another job of an identity it has by utilizing downtime and wishing for it to be nerfed.
SE did better for job design to encounter design when they just did what they wanted instead of trying to appease whiners.
