I am fed up of reading posts were people are saying "nurf this" and "buff that" or "it was better before". So ive been thinking why not have ghost engrams such as rare and legendary or even a quest to get a high LL ghost. We get quests for armour and weapons but not ghosts. I dont care about artifacts as they are useless. Bungie come up with a quest line for an exotic ghost and see what happens.
