So apparently they're not bringing grimoire cards with destiny 2. They plan to actually have characters with personality, and tell the story in the game. This is a possible huge step forward, makes me a little more optimistic. Still reserving judgement until the beta and release, but so far I'm hearing a lot of improvements that are drastically needed. https://www.forbes.com/sites/erikkain/2017/05/21/bungie-is-ditching-grimoire-cards-in-destiny-2/#3d3af0f09beb
