Had a tough time too, but we found an area to kinda of camp. It's on the left side as you're facing boss by back wall. There's a walkway with some walls to hide behind and a clear shot at boss to take him down quick. Be careful because the game does teleport people around map. Not sure if that only happens if you stay in one area for too long or not but its really frustrating. What do they want us to do, run around the map spraying bullets and firing rockets? I'm sorry Bungie but taking cover in a specific area ACROSS the map from spawn point and picking off ads and boss fron a distance is a good STRATEGY not a CHEESE. Any ideas on why they teleport us or when its programmed to happen? Is it random?
