I think YouTube personalities could be beneficial to the Destiny community but currently they take a lit of risk saying anything negative about the game. If there is anything communicated to bungie it's probably not in the public eye for the most part as this would possibly damage their relationship and future considerations for events. Let's be honest, they make money though/because of Destiny so I don't see them bashing it too much. They have the voice and platform to communicate with bungie though, so there could be a benifit to having that. I doubt any of them would take up that mantle though due to the community at large. There isn't a lot to gain or win for most of them.
