I am not sure if they can change or even want to change because their business model is profitable for them at this stage. As they have a good fan base 6% of the original game purchasers whom choose to continue to throw money to TV when asked. If they had any intension of changing , we would see The Taken King introductions posted on Bungie.net instead of third party websites , we would see Cosmo and Deej interacting with community as Community managers , we would see Luke Smith keeping his mouth shut etc.. Many things changed in Destiny up to today , the only non changed thing is the lack of respect Bungie showed towards Guardians.
