Missing item

Hello!
I have nice geared Death Knight and I thought about transmogs. But I was surprised that there, in End PvE NPC, is whole set for Death Knight EXCEPT Necrotic Boneplate Pauldrons one. Is it a bug, your miss or your purpose? Fix it please, because these shoulders are great ;_;

Buy the Backbreaker Spaulders, they are the same model.

But the only one plate shoulders I can buy are Brackenshell Shoulderplates

GMs fix it, please! Warsong players need you too, same as Lordaeron...
