I remember when it was "common knowledge" that you couldn't loot anything above level 16 from chests behind doors.
Back in March I was playing in a game where a pug joined in zone 4, ran up to the rogue door I had walked past a minute earlier (I was an assassin, but the host didn't seem to want to open doors), opened door, hit the chest, then got wrecked by the Revenant it spawned.
I ran back, killed the Revenant, revived the pug, picked up the gold, then we proceeded to clear the zone, all the while the host screamed at the pug for opening the door.
I got annoyed enough to put my mic in and tell him and the silent pug that there was no harm done, we were still going to clear, and now we had another item to collect after we got out of the game. At this point, the host notifies me that it's not even possible to get anything above level 16 from chests. I told him that was BS and that he didn't know what he was talking about (I had pulled a Sulevin Blade from a chest a week before that, and a Punched by the Maker sometime in December.)
The host continues to scream at me for the rest of the game, saying that he knew what he was talking about, he was high on the leaderboards and had 2000 hours in the game, and he started dropping names from people high on the leaderboards, saying that they say the same thing about items looted from chests.
Some time in the middle of our exchange, a 4th player whom I recognized from the leaderboards (somewhere between 30th and 40th place) dropped into the game. As we finished and loaded back to the lobby, it was dead silent. I checked the leaderboards, and lo and behold, there was the host somewhere around 95th place. I told him that 95th (or whatever it was) was not really "high on the leaderboard" when the leaderboard only consists of 100 people, and that he should go play Call of Duty if he wants to impress anyone with all his BS. He called me an a##hole and left. After about 15 seconds, the person I recognized from the leaderboard plugged in his mic and said "Snake, you're on the leaderboards, right?". I told him I was somewhere around 15. He then told me that that was the funniest thing he had witnessed in DAMP.
The two remaining players and I played a few more games together, and we lived happily ever after.
The End.
TL;DR. Know-it-all host facepalm.
