I was going to preorder but I always like to know what the expansion is about before buying. I have been playing MMOs for a long time. All failed MMOs always have a few things in common. One they get a dev team who will rollback previous work. Whenever a Dev team does a rollback that is a sign that the team (current or past) is suffering incompetent leadership. Now a rollback can be good but on the average it only good when a new Dev Team initiates it.a Dev team that rolls back their own changes generally should be fired.Two, no coherent vision, they have no clue what the experience is supposed to be so every change is a pendulum swing. Three, the attempt to minimize work for themselves. Everything is half-measures and stop gaps, never a true confrontation of the real issues. Now Bungie has added some new entries. Such as the promise to fix what is broken before the new content is release, which just admittinv your content is fubar'd before it has even been released. I am pretry sure if we got to look at the company's internal emails, that Bungie's Dev team is under a crisis of leadership.
