Tips - If you don't like using TLW, don't use it. ANY kill counts so long as TLW is equipped. If you can snipe and get more kills, or manage a good heavy kill streak, do that - Learn to use TLW as what it is now - a close range monster. I do mean close range, like shotgun range. It's just outside shotgun range, but in there, it's like it was never nerfed. Lot riskier though - Play Mayhem modes. Since you don't need TLW kills necessarily, go Mayhem and use your super. If you're a Sunbreaker, take advantage and go ham. If not, play as carefully as you might normally, and you'll probably see more progress than in a regular game - Don't try to do this bounty AND the exotic sword bounty at the same time. You'll just get neither done - If you're on a good streak and it ends/you're scared it will, take off TLW. Equip something else. Rather than continue and risk losing your progress, save it for another match, without having to quit - Be patient. It might take a fair few games, or only 4 (I got well lucky). Just don't expect to finish so soon because you won't be disappointed if you don't, and you will be chuffed if you do EDIT - one more thing - KD matters a lot here. It's not a base increase for kills and decrease for deaths only, there's more. Kill streaks, multi kills, other things (e.g. Phantom) all yield progress too. Rather than get a load of kills and a bit less deaths, try for some kills (10-15) and minimal deaths as best as possible. It's much better to go 15-5 than going 30-20
