Play a lot. You'll get better. People love to say "get good" ... you may not "get good" but you'll get better. If you are running Titan or Warlock, be sure to run the Void subclass as supers and grenades count. Don't play too aggressively, pick your battles. Play on Control maps ... this is definitely scrub advice, as the players are focused on capping zones and you can pick off stragglers. Don't be afraid of using a non void weapon occasionally ... better to get a few non void kills than extra deaths! Void shotties, void machine guns are your best bets. Uncommon weapons do just fine. You play crucible enough, a BTRD will probably drop ... roll it to be void and you're set. (I'm bad at sniping, but some people rock at it. Maybe you're one?) Word of Crota hand cannon is a big help. Atheon's Epilogue, not so much. Hope it helps. My first Thorn bounty took forever ... the second one wasn't near as unpleasant. (Bear in mind that the Xyor portion is no walk in the park either ... I recommend getting a team together for that as well)
