Not getting rep

CAN’T GET ANYMORE rep from doing the lich king dungeons
and i am nor way maxed in the rep from doing them please help

Are you wearing the tabard for the rep you want? Wearing a basic tabard in those dungeons gives rep to like the kaluak and sunreavers (dont remember the alliance version). Also are you doing them on heroic? Except for like HoL and HoS i dont think any of the others reward rep on normal.

The tabard only works in Heroics.
