The lore community is so shitty because the lore is so shitty, I know people will defend it to the death but the problem is bungie did a shitty job of making the grimiore. There is tiny and ambiguous hints here and there, but three years in there is still no overarching theme or message being presented. Furthermore, instead of expanding on existing interesting characters, every expansion is another little wormhole that seems only tangentially connected to the previous story and lore... I mean FFS it's year 3 and we haven't addressed any of the themes in vanilla destiny. Sloppy lore (even through a substandard "grimiore" system) creates a sloppy lore community. Hopefully D2 will bring it back to the main storylines and characters, but I doubt it.
