Finally, one of the big name influencers for destiny 2 comes out and lets people know about the truth with "skillful players" in destiny 2 PvP, and to an extent pve as well.
People are self-interested. It makes zero sense to self-handicap when the ultimate goal of any activity is to complete it (and in the context of PvP, to win). I have no shame in admitting that I rarely use anything other than DRB/ID, NF, and Truth. I want to win as consistently as possible, not to struggle unnecessarily. Just because Cammy is likely a masochist to some degree doesn't mean the rest of us share that desire.
