Battle of Darrowshire (Raid) Quest not working?

Okay so this DOES work, 10/4/2019

  1. be in a raid group, you need at least 10 ppl, tanks and heals
  2. one person in raid places bag down to start the encounter
  3. wait for Davil to spawn, mark him, keep him alive by having your tanks taunt and dps hard, Davil cannot be healed by you
  4. wait for horgus to spawn, kill him with Davil alive to move to phase 2
  5. Davil will RP die, this is normal
  6. wait for Redpath to spawn
  7. same as phase 1, stay on redpath do NOT let him die
  8. Redpath will randomly travel to the north eastern side of the fight, off to the right from the main path into town where the blood letters spawn
  9. (heres what we did not sure if its 100 percent correct but it worked)
  10. Let Redpath attack blood letters but DO not let him die
  11. ignore everything else, have your whole raid stand on Redpath and dps down everything
  12. the other guards will all die, have a mage run out and aoe gather up non-elites that spawn and bring them to red path as well to kill
  13. After about 15-20 minutes, and alot of dead bloodletters, the server actually shuddered for a second for the whole raid group
  14. Red path began franticaly running to different parts of the camp
  15. FOllow him and keep him alive
  16. redpath was about 20 percent hp when he finally made his way back to the front of the road where davil dies
  17. at this point the evil redpath spawned and redpath either died or disapeared
  18. kill the evil redpath, than everythign despawns server shuddered more
  19. talk to ghost of redpath to complete quest

We tried 5 times, different techinques each time, this was on a thursday night
