I used to be able to farm stuff from the Wraiths at the Raffen Shiv camp (the place where Riders on the Storm mission takes place) as well as level up skills, but the Wraiths are not respawning anymore. Did they change this in a "patch"? If they keep altering gameplay for the worse I will have no choice but to resort to duping items, something I have been avoiding to remain legit. This area was the only good place to farm for the Phantom weapon mods which increase rate of fire.
