Team Fortress User-Made Concept Update

So there's a new "Team Update" for Team Fortress 2. While there's nothing special about the update, there is a user-made concept update that's been posted on many gaming sites. The concept calls for a new support class, the "guard dog" class. The author even received a response from Valve. Personally, I thought the letter was much funnier than the class, which was also interesting in itself. You can check out the concept here.
