There must be an event which triggers here which causes Bandits to completely swarm the entire Seraph camp, but even when the event is not active the respawn rate of the bandits are at a mega high, constantly killing the NPCs.
It makes the whole camp kind of useless, especially when you use the Waypoint there and are immediately put into combat from one of the many bandits.
(This problem has been here since September 2012)
