Totally needs to happen. I hate that so many people will bash on this with the idea that "oh, what's the point of new content than if it's not better??" I'll tell you the point: diversity. You can become legend with the tools you want. Maybe it's from the VoG, maybe it's from Crota, maybe it's from the Iron Banner. These things shouldn't become obsolete, but make every character different and give us new toys to play with. I really hope Destiny 2 keeps these things in mind.
