My take's been that MSQ dungeons shouldn't have been made faster or had telegraphs hidden until last minute, or at least not have been so strict on their enforcement. The last boss of the Cenote dungeon's got some strangely strict positioning with the knockback mechanics, and the second boss of the latest one catches quite a few players with the one move where a bunch of aoes go off one after another. The phoenix down change did help counterbalance it a little, but it should've happened much earlier.

Also you know what isn't as strictly enforced in normal content? DPS checks.
Playing a job well, while encouraged, is a lot more optional in comparison and job complexity allowed players to adjust the challenge for themselves but we don't even have that now. They went a route where the game caters to a much more specific crowd than it used to.
