What you're thinking of is what they did in WoW with some characters that you can play as them. Personally I say have a cut scene at the beginning and the end of the exotic quest. What Destiny needs is to add more of it's lore into the game itself. This is rather redundant but hopefully Destiny 2 can apply this. This was Activision's fault when it came to the grimoire cards. I believe Bungie wanted to implement more lore into the story but you know Activision. "Make it a Call of Duty and it'll do fine." The launch of the game proved that didn't work and the lawsuit finally freed Bungie from Activision. To implement lore, I say do what they did in the Elder Scrolls and WoW. Have the option to have people like Cayde, Zavala, etc. to be able to talk to them and get some possible back story or points of interests. Second, in Elder Scrolls I liked the books and scrolls that they had. We were able to read them so I say have that option available within the game itself and not solely on the website. In Taken King they had a few places where you can scan on your own with your Ghost. I say do the same thing but expand more on it. Have let's say Eris, give a quest to study the Hive bases. You go to the base and fight obviously, then as you explore, special objects or columns with scriptures light up. You can scan them and add them to you encyclopedia (similar to that of Mass Effect's). You go back to Eris, complete the quest or mission and you get some more lore information. Or better yet, let's say you do an optional part of a quest. You get something more out of it. Like a special cut scene of her and the fire team fighting Crota. These are a few examples I personally will explore more on some possible ideas on a video.
