I mean, the guy only wants perfect 5/5 rolls for the meta and doesn't seem to plan around edge cases, backups, or potential buffs/nerfs so of course he's going to scream about how you need to delete that 4/5 roll you got to drop after a full day of farming without anything better coming along. Destiny is his job. He has the time and incentive to throw away near perfect weapons and armor rolls because he'll play enough to statistically see the exact thing he wants to drop. I don't know why anyone lets him comb through their vault to trash things except as a meme.
