Yeah man, Some people delete stuff just to replay. My mate went from level 3 - 10 in a couple of hours last night. basically, its just a matter of playing the story, doing a few bounties and buying dark below Armour and you are back. At least Xur will have new cool stuff for you every week now! It will be better even! You are looking at about 5-10 hours per character. She's all good man. Perfect time for it to happen, now - when there's crap all else to do.
