How do you know this? They added lvl 60 requirement to head/leg they might as well do this to shoulder enchant. Besides a GM could always manually remove your item.
And you don't think such an obvious exploit won't be punished? Will definitely report anyone who has one of those enchants and see what gm's think. If they won't do anything I'll get shoulder enchant too. Head isn't worth it on goggles for rogue.
Hey, I'm also from EU , so sadly I can't check it either. But someone told me this person has it and that it dropped from the Un'goro Gorillas after 2 months of killing. I'm just farming it too right now.
