As someone who works in a corp with a lot of NPS junk in it, I can say with certainty that the vast majority of people that have any comments at all are the people that are displeased with their personal experience. The people who are happy or indifferent almost never participate in surveys or petitions or leave comments, and when they do, all the detractors gang up on them until they leave. I don't think anyone here should say anything about 'the majority of the players say', unless you can prove actual numbers.

Your point will be just as strong leaving those comments out. Just stick with personal experience, or give your honest thoughts. It's just being a good interlocutor.
