I feel it's more people wanting things to work as designed. so they can also focus on asking things to be changed, or added once all is as designed.

one can say a tier dies once a impactful amount of players have their gear. but as always, a good amount of players disprove that. just like you can say enough players keep running the content for fun. despite many not wanting to be forced to do so.
<it's both, but enjoyment sure does come easier once it's no longer mandatory for what you want out of it..,>

for some it's greeed.., for others is being equipped to enjoy the content that comes out seamlessly.

doesn't help the way the content works. and some classes work leading to different levels of players filling out different roles.
So a certain Dev saying. just play Healer. gives more fuel to ask for gearing change.

which tbh, is just a sign of the way times change.

there is no negative here if they do it right.
But doing it right takes time. since they'd have to do alot of research else.
you guessed it, angy players
