Destiny 2 World Lead Steve Cotton recently revealed to a fan question that Grimoire Cards will be dropped from Destiny 2. Cotton stated..
The answer to that question is ‘no’ and the reason it’s ‘no’ is because we want to put the lore in the game. We want people to be able to find the lore. All the story is told through the Adventures, it’s told through the characters in the world, it’s told through the campaign and it’s told through scannables you find throughout the world.
Grimoire Cards were a complaint in the first Destiny game as it took away from the game’s lore and were locked on the Destiny website.
