Surveys would give filtered, clear feedback to the development team about what the majority of the playerbase wants at any given moment. But they would need to be in-game surveys to reach the majority of the playerbase, and probably opt-in with some kind of incentive.
The reason I think this would be fantastic for the development of the game is, currently the feedback being received is a jumbled mess of either legitimate constructive feedback, toxic feedback, trolling, etc., and I don’t feel like its a reliable source. Imagine being able to ask the questions you really want to ask your community, and getting back clear, concise responses with an accurate percentile measurement to back things up.
That is all. Thank you for listening to my TED Talk.
