I really like the Destiny's history and prehistory, for lack of a better term. All that lore about the golden age, warminds, the Darkness and downfall of mankind. I thought these were the interesting questions of the Destiny universe.
With Destiny 2, it feels like they keep writing characters and then throw them away. Every expansion there's a new adventure with a character I don't care about. I feel like they don't spend enough time on how the world of destiny got to where it is.
You can say that the grimoire cards were a dumb way to deliver lore, but I liked the content and can recall them much more better than anything a single character has said.
