Hey! So it seems you got your answer already from this post, yes, there are other exotic bounties that don't require you to play PvP. You have the bounty for the Invective shotgun which I myself love but find it to be more up close and personal than I like to play. The k/d spread is exactly how you do described it, pretty much keep getting more kills than deaths and you will get it in a few matches. But it's simpler than that, assists count on your meeter so you don't have to get that final blow for every point. This can make capture your best friend as you can run with other players and increase your chance of getting points without dying. Also it's smart to actually avoid the capturing zones and instead keep an eye on zones to defend, the moon on particular was fun due to the turrets. Hope this helps if you've decided to keep the bounty. If not, best of luck to you on getting a more suitable bounty without PvP segments!
