Blizzard has stated that the craftable iLvl 377 PvP accessories were unintentionally available at the beginning of Cataclysm Classic. Since these items were originally introduced in Cataclysm patch 4.2 as catch-up gear, Blizzard will be removing these items from players who have already crafted them.
We’re currently working to fix the setup of Professions that can unintentionally craft iLvl 377 PvP accessories.
We intend to remove the items from players that have them, as soon as possible. So we suggest you don’t invest in them.
Thank you.
