It was my first run through regular Grim Batol. I was in a guild group made up of the movers and shakers, including the guild leader. I was still a fairly new member of the guild and had never actually run anything with the leader in tow, so I was feeling on my guard. This was the first time in GB for several of us, so things were getting spelled out as we went. The bombing run went adequately, and so did General Umbriss. I'd managed to dodge the worst of it so far, and my DPS was holding up all right, so I was beginning to puff out my chest and not feel like a total failure.
We crept around the corner and the tank began pulling the trash leading up to Forgemaster Throngus. I peeked my head around the corner to see what was going on ... and my water elemental promptly pulled Throngus and everything else in the entryway. We all fought valiantly but suffered the inevitable wipe.
Fortunately, everyone was in good spirits about it and laughed. It's become a bit of a guild joke, and I now get told when I should stay put, but I was completely mortified and wanted to slink out the back door with my draenei tail between my legs.
What moment has made you want to log off in shame and never return?
