The Fire Shaman at Iron Marches offers an interesting group event battle, and the Scorch Warband offers some interesting lore when spoken to after the event. However, because the Shaman is in a map corner away from waypoints, and because he doesn’t offer a substantial reward, he is virtually ignored. Unless friends or guildmates are on and willing to help, a player is stuck unable to defeat him. My suggestion is to remake him into a timed world event boss with a chest reward at the end. This would encourage people to join the fray, and the Scorch warband lore would be more accessible.
