I am level 35 with LW at 190 and I am unable to learn anything from Hahrana Ironhide. She states that I haven’t gotten enough experience to visit her yet I need to learn patterns she has such as “Guardian Gloves” and “Dusky Bracers”.
I believe you need to have at least 200 skill to train with any master trainer. This is SoM/vanilla classic and not TBC classic right? If so, this has always been the case and is not a bug.
EDIT: Try going back to Una in Thunder Bluff and learn the recipes from her instead. Wowhead is wrong about which recipes are available from her.
