Do you have anything to support YOUR point of view? Any reasonable data? Or just forum goers being angry at something talking about stuff they don't like? If you don't, don't bother mentioning it. It's anecdotal.
I just gave you the same reasoning you have and you think *I'm* pushing the narrative here? Jeez....
and yes... "ultimate proof" sure...

It's not like Blizzard pushes something, then doesn't anymore, and then does again, and then doesn't.
Oh look, talent trees. Obviously they were "hated" - away with them!
Oh now they are back - surpriiiise....
There are way more possible reasons for them to discontinue this than you are thinking about. Not everything is related to what players liked or disliked. It's pretty likely that with garrison, the reason it's discontinued could be something as simple as performance issues.
