That's exactly what happened to my boyfriend last night. He joined a raid group with one of his friends, and didn't know the "leader" of the group. So the whole time, when he's directing them, he's doing it wrong, and they're dying (they didn't know how to do the raid, so they didn't know why they were dying), and he's yelling at them saying they shouldn't die and to basically be flawless the whole time. I'm like, wow, if I was there, that guy would be kicked. Either that or we'd leave and make our own group.
