I never deleted my old Destiny 1 Guardians, but I never went back after I left either. I thought I might, but new things came up to absorb my gaming time. Not deleting Guardians doesn't mean a thing, really. If people are fed up and stop playing but hope for something to lure them back, and it never does, then it is still a blow against the game.

That's a little unfair. He said he might be back. Let him try a few other games. It might be sooner than he thinks.
