On 11/03/2002 I killed set out to get this BP. Before I knew it was on the forager cycle, I was killing hunters as well. A Trakanasaurus Rex spawned, and soon died. Strangly enough, the very next spawn was a mob named Ffroaak. Ffroaak didn't drop anything, but it was interesting that two named spawned in a row. Anyways, I was then informed that the Crusader that drops this chestplate is on the Forager cycle, so I focused my efforts. After about an hour of killing the foragers at the Swamp of No Hope zone line, my partner (56 warrior) and I had the luck of seeing the Hangman spawn. He dropped the Hangman's noose, but you guessed it, another named spawned right after him, the Crusader. Both of these times tow named spawned in a row, and all three named that were said to drop something did so (Trak's tooth, hangman's noose, and ceremonial iksar chestplate). I am not certain if these mobs always drop these items, or if I just had a stroke of luck. Hopefully this information will ease the pain of the quest for this much saught out item.
*EDIT*
Hunted the forager cycle a bit more and it turns out that "two named spawning in a row" was just a fluke. Sorry for not investigating further prior to posting.
