There is always that burner who’s done it all, today, before breakfast, like they do every day. They have dust for blood, knows everyone, has been burning twice as long as you, and are quite willing to tell you that it’s been done before, it was done wrong then and you are doing it wrong now.
Part curmudgeon, part internet troll, the Burnier-Than-Thou is an asset to any camp. Use them as a reference, ask them to show you how it’s done, get them to call in favours for you. They will either step up, or have a mission from which they don’t return.
