A couple of ideas I had; I'm not sure if anyone else has thought of these (I wouldn't be surprised if they have.) One way they could bring back old campaigns and raids is to implement them into the Timeline. For example, in the Throne World, we have the option to replay the story missions on the Throne World map. They could implement that into the timeline and let us play the old campaigns (story missions, adventures, strikes, etc.) and the old raids. Not sure how likely this will be given what's going on with the Red War thing right now... The other idea is for weapon crafting. They could give us the option to enhance the other perks for our craftable weapons (Barrel, Magazine, Origin Trait, etc.). Just a couple of ideas I had floating in my head.
