I actually had the exact same experience. Today I threw together a team with 3 friends and 2 randoms for a quick normal run, I don't need a 6 man team but hey last week we took through 2 27s that had never raided before. So one of the guys joined and he was perfectly chatty, just general banter and the other joined and said nothing which I didn't really care about. So I solo'd the abyss and everyone gets teleported and gets there shit rewards We do the bridge completely legit with 5 across and 1 idiot (one of my friends) dying on the far side. Then we immediately do down the shrieker corridor because I had some gjallahorn ammo and I'm abit of an impatient bastard at times. Still no sound from the 6th player. So we drop down and I do my usual and just go and call out '2 left with me and the other 3 head right I don't care who' and the death singer goes down. So I check up on everyone's load outs and tell them im running sword. Because I take down crota in 1 sword on hard using supers I ask the titans to go drop their bubbles and as many orbs on the crota platform and then all of a sudden 'Hey crash, do you want the orbs on the left or right side' It was a squeaker, a real wild squeaker, this player that had not died and had remained calm all the way through without a single mistake was one of 'them' And he was asking a question that wasn't.... well, stupid. And i reply 'Yeah i go up on right side' And i watch him drop his bubble on the right side, then go and gather orbs from the death singer encounter and spawn a few more bubbles giving me orbs for crota. So once we are all ready and about to step onto the crystal platform I do a call out on who has and who needs rockets. Everyone informs me that they're fine and have synths. Except the squeaker. So I ask him directly "hey -xxxx- do you have rockets" "Yeah i have 6 gjallahorn and 12 synths on me" Again I was completely flabbergasted, he had rockets, Infact he came prepared with synths, he wasn't waisting everyone's time with the heavy ammo exploit. And that was it. We killed crota in 1 sword and he thanked us for inviting him and he left. I guess they aren't all bad
