What I liked: collecting all of the weapons and armour. The community competition and data published. The nostalgia.
What I disliked: the pressure of getting as much done in so little time resulting in repetative grinding.
What I expected: Faction Wars - things like 3v3v3 crucible playlist and strike matching based on allegiance with scoring. More competitive data. D1 style of the faction being able to be represented indefinitely after the faction event for point and gear accumulation.
