I've been hunting poachers in Jaggedpine for awhile and can add that the named do still drop magic items besides the leather/chain neck/boots.
Zed still drops the clicky illusion mask rarely, but it's not clickable from inventory.
Elisha still rarely drops the stampede sword and the proc has been improved greatly, I can't wait to start using it on my ranger.
Killed Vaurian a dozen times with no drops, killed the other one (can't remember the name) a few times with no drops.
Oh and the Timber griffons still drop the nice range wisdom item rarely (griffawns don't).
