The Lessons Not Learned.

[Kazhar]

It's usually people like this that have the biggest egos in the community, believing they have all the right solutions. I recall somebody saying that players are experts in finding problems in a game, however they're not capable of coming up solutions to those problems and to me that holds very much true these days.

Don't know if it comes from there but it was part of Mark Rosewater's 20 years 20 lessons presentation at GDC 2016. This is also common game designer wisdom. Listen to criticism, not suggestions.
Which is why I believe criticism is healthy for the game even when it's not "constructive". Just saying "I don't like X" is a more valuable information than people give it credit.
