People who say it's too hard are understandable. FFXIV has terrible difficulty curve, it doesn't teach you how to be better at the game as you play it. There are subcommunities of rpers, socializers, and plotwatchers who really only use the game as a social media platform. They aren't interested in the gameplay beyond clearing mandatory content one time ever.
The fault is on Squex/CB3, not on them for not getting good, because the game doesn't teach them how to get good.

In line with wanting glamors and such from content they can't clear, they seem to have forgotten that they are playing a video game, not a 3d avatar chatroom.

The game lacks reactive gameplay, the healer problem is the perfect example of that. The difficulty is in perfection of execution, memorization of puzzle mechanics with no rng. It's more like studying for and taking a test, like savage raids, and normal content is just the lite version
