I mean, I sometimes enjoy trolling forum whiners myself. But, I think community morale can negative consequences in much the same way that bad corp morale can lead to players jumping ship or stopping from logging in. Not only do I think that bad community morale lowers veteran retention, but I also think that all this complaining normalizes it. I know there are still plenty of players who call out forum whining, but there are also a lot who support it, and this creates a culture where some players think that the best response to adversity is to take to the forums and bitch, versus trying to adapt and grow as a player.
Anyway, I may not be able to change the minds of that many existing bitter vets, but perhaps I can stop others from following down that path.
