I got his problem beat.
While playing a game of L4D2, I was jumped by a Jockey while I still had full health. You would think the only bot would help me, but NOOOOOO. The others were dealing with a zombie horde and special infected, and the damn Jockey rode me until I was incapped. Remember I had full health before. This is the sad part...
I had just killed the Charger that knocked Coach down, when the Jockey hit me from behind, no noise heard, so I guess he spawned just around the corner. Anyways, Coach FOLLOWED us the whole time, with his back to me, walking backwards against the Jockey and I the whole time until the Jockey dragged me through fire and I was incapped. You would have to have seen it to believe it. Then another Charger hit Coach as he was helping me up, and because my teammates were incompetent, we all died.
Talk about a bad game, we had just started the first bloody map of Dead Center!!! DOC, we have to play again sometime...there's just too many idiots joining my games.
