You can only use Kvhostov. Nothing else; not grenades, especially not supers, and no melee. Just Kvhostov. However, if you manage to kill anyone with it you are a lvl 90 haxor. So, don't get any kills and only wield Kvhostov. Actually do get kills, bc if you don't, you'll get an exotic and people will get butthurt. In fact, only play control and only get points by capturing flags. Then you're still a scrub, but the highest possible level of scrub, as you did not use any weapons and the only people that will get angry are people on your team. Actually, just never go into the Crucible. Spend all your time playing the first level over and over again. And never let someone join your fire team, as they will eventually get angry. Just keep killing level 2 dregs.
