I guess for me I’d feel like I’ve read about all these cool events in HD2, and they’re gone and done and I can’t replay them, because they were live events only.

Compare that to something like Mabinogi (which is still an MMO, but doesn’t follow the same live-service philosophy), where you can start as a first-time player today, and still play through every campaign/ storyline since its ~2003 release (and there are a LOT of them).
