I can't speak to the rolls/archetypes as i've not looked myself. But for the broad question I feel like i'm satisfied with what we got. Seems to be a tad bigger than shadow keep. Considering Shadowkeep is the minimum i'd expect out of an expansion that seems fine. Though I don't know how much of this is because we have a brand new subclass. Luke Smith admitted recently that they can't really make forsaken/TTK sized expansions anymore since the departure from activision. Which is a bummer but is fine for me. Destiny as a franchise became very clear to me as a game that isn't fun enough to play "just because." I've always been far more invested because of the lore/story side of things. So I guess if you're someone who only cares about gameplay itself than I can see why less content (esp with sunsetting) stings. However it's just the reality we have since Bungie decided to go independent. I'm willing to work with what they feel they're capable of. It seems like they're mostly receptible to feedback as we see a continuing of them attempting to improve the game. And that's all I can really ask. Back when Bungie announced Destiny and showed us concepts/teased us with their pitch my mind went flush with possibilities. It took awhile but I eventually learned to accept that what I personally want from the series isn't the same thing they want. This has helped me come to enjoy Destiny for what is is. And probably why I don't fret about things as much as most do here.
