Well I'm back from my comfy bed read up on all the recent posts. I pretty much completely believe Guan Yu's role claim now... but Dun's backup argument does not seem to be nearly as well fortified.
The way you play your "8th guard" is pretty interesting, wasting a stoplynch, and letting very useful townies die. Now I understand that you want to continue to experience the game, but a decent strategy can make the game a much better experience.
