I saw an article posted about this a couple days ago and I thought it was terrible. All the people who went in like they usually do to grind for something they really want, only to later be locked out of being able to grind for a desired roll. Bungie knows this is what the IB players do. If this was done deliberately (only saying cause that I am not sure on), then it is a REALLY sh*t move on Bungie's part and is, yet again, another thing added to the "Why people are leaving your game" category.
