Has anyone noticed that it doesn't seem to ever come from player feed back?
Just to pick out a few from legion onwards (I could go back further but just for a bit of brevity) .
Legion: players loved artifact weapon appearances but disliked artifact power. Blizzard trashed the cosmetic parts of the system and kept artifact power going forward.
BFA: Players despised all the power systems that increasing got more and more obnoxious as the expansion continued onwards. In shadowlands these systems didn't just survive they multiplied.
I don't even see any self awareness in shadowlands since in 9.1 they added a massive time gate tied to grinding via gem sets they effectively lock you out of higher level raiding till you have them. I have to admit it is starting to feel more like spite then simple ignorance of what their playerbase wants.
