I don't know about red war, but definitely, Bungie should make a better new light experience. TBH red war was mediocre at best, and with whole lotta things that have happened since, (Cayde 6, Calus, Caitl, Osiris, etc) I don't think it would help, rather confuse new players. Also, abilities don't work how they worked back then. Just make this Navota story a bit more player friendly and a bit meatier, that's all it needs, and then at the tower Zavala, the Drifter, Ikora and Hawthorne explain the rest.
