Seasonal stories especially are extremely important to the story and without them the game would still feel incomplete. New players would still get confused by the story because Crow will just appear out of nowhere in the Final Shape, entering the Pale Heart will not make sense, most villains will come out of nowhere and seem way less important (especially Calus and Maya), Savathuun will go from being dead in Witch Queen to being alive in the Final Shape, Amanda Holiday will just be dead off screen, Saint-14 will go from being dead in Curse of Osiris to suddenly being alive in the tower, etc. An abridged quest line for each season with all of the missions (maybe get rid of the sever missions from odd numbered weeks, as they are redundant gameplay wise) and exotic quests should be enough (a legendary campaign would be neat too). The exotic quests should return too because of progression (unlocking everything from the kiosk is not a good method of progression) and many of them have important lore. Also some of these missions are just really well designed and should be experienced by every player. Lastly, I know some have been suggesting only bringing back the cutscenes, but I believe that will feel like a cop-out to anyone trying to play the story. People need to actually experience these important stories for their overall understanding and enjoyment of the game and its lore.
