Hello. Preface by saying I noticed this on a level 47.
The corrupted aspirant gear sold in Orgrimmar now shows “requires level 47” but gives an error message of you must reach level 50 to purchase.
The three CA trinkets (for gold instead of honor) Medallion, Sigil of Adaptation, and Relentless Brooch CAN be purchased, but when attempting to equip gives an error message that one must be level 50 to equip.
