Ah yeah sorry, I should have worded that better.
Thing is, this has been a concept since Blizzard talked candidly about it back in the early WoW days (and since then some other devs did, Awesomenauts for example), players by and large are quite good at telling you that something is annoying them, and to a degree what.
However, experience has shown (and this matches with my experience in business software, where similar issues exist if on a different level) that even in the context of explicitly being asked for feedback players are very bad at telling you why something is annoying to them, and what they would like instead.
The same actually goes for the flipside, albeit it's of course more rare as happy players don't leave feedback as often as unhappy ones: Players can tell you that they're happy and to a degree what makes them happy, but not really why that thing makes them happy and what should not change lest it'd no longer be awesome.
So basically, from player feedback, take the "if" and to a degree the "what" (at least as a general pointer) but not the "why" or the proposed fixes.
And that's not a negative in itself. Of course the onus should not be on the players to provide this, they're not developers. But it becomes a problem in the modern social media age as players of certain groups tend to form a sort-of cult around some bigger personalities, and in the process of which these personalities get paid for providing more and more and more detailed and more detailed thoughts, which also means they'll provide ideas and hence a large group of players takes these ideas as if they're their own.
And then as developers, you get peer-pressure to react to these influencer thoughts one way or the other. Which is a bit weird, as they're just one person, just with a bunch of people who likes hearing that voice blabber incessantly.
And like a project manager in business software, it becomes surprisingly difficult to ignore these "larger" voices sometimes, but listening to them can be utterly destructive, as in the end they're no better than any other random voice. And sometimes less so, because they focus on a thing that's less related to gameplay and more selling the appearance of gameplay, after all, that's how they make their money.
Sorry, got way too wordy. Point is, I don't mean devs should ignore player feedback, but they need to be careful to not read too much into it either. That's how we end up with homogenized jobs after all, players crying for balanced raid performance constantly.
