People have been asking for changes to the AH since Vanilla, sorry to disapoint you. You would have known if you had been actually around.
While I want PvP vendors back, it wasn’t possible due to how rewards ivl is tied to rating. They did say recently in an interview that in the next expansion that the best PvP gear should come from PvP. I hope that is true.
People seem to think that everything they want should be acted upon, that’s not how things work. You give feedback, they either agree or disagree with it and act on it. It’s that simple.
