Just have the last word gun equipped and run SRL. Don't crash and you'll get 3 points per race you finish (positions don't matter). Then it's just a matter of spending 10k glimmer, shooting people in crucible with shotguns (or a lotttttt of yellow bar ads) and killing the shield brothers with a shotty. It's not cheating. It's an alternative route to completing the quest. These elitist idiots can judge and cluck all they like. Does it matter to you?
