This is by far (short of the named who drop the augs only) the easiest event in CoA.
If you are a main playing ranger and think you have no use for it, odds are your gunna loot it sooner or later. As the first event in CoA. All his drops are now common for all.
If your an alt sooner or later you'll get it for an alt too. All his drops are common for a CoA farming guild.
If your an INT silk class caster, odds are you'll end up with it also, just to prevent rot and have a bragging right.
Later on, towards AMV or Hanavar you'll see less items rot, but some eventually will. Nothing from OMM will rot as no one does him. He just too much of a PITA for the loot given.
