This also happens in every single player game with any kind of builds/talents/choices too. Forums and subreddits for any kind of game with choices are always flooded with “but what is the best” type of questions.
Has absolutely zero to do with MMORPGs.
A large percentage of modern gamers are lazy, uncreative, and can’t think for themselves. They want everything and anything and they want it the easiest way possible with zero chance for failure.
While I agree with your points, this extends far beyond the mmorpg genre and is a problem rooted in modern gamer culture itself.
