Last night I was trying to bash out the last bit of the exotic sword quest and the other players kept ruining it for and killing certain enemies so I was on my fifth go and ended up with two kids who did legitimately accidentally kill my guy but I said whatever I'll help you get yours and then they stayed in orbit and did it again just so I could finish my quest. I was pleasantly surprised and half expected them to leave me after they got their swords. Cheers guys!
