Fighting [b]Crota in Hard[/b] with [u]randoms[/u].
People keeping rushing outside the starting room and saying "The timer didn't start yet; don't worry about it".
Then, we'd get back from Ogre round and he'd be about to enrage and they'd say [i]"I've never had that happen before and I've done the raid at least 50 times!"[/i]
No shit; they triggered it early.
[b][u]By the way[/u][/b], to people who say they have done raids way more than they actually have, I actually spend time doing them for other people and I've only done Crota [b]37[/b] times and Vault [b]36[/b]. Seriously, [u]stop[/u] saying you've done it a crazy amount of times. [spoiler]You seem like a tool.[/spoiler]
EDIT: Just the two responses under this remind me why I don't post in the forums. No constructive criticism; just "Look at me!".
