So if i understand this well....The best way how to farm these (mainly dungeon quest items) is to run old Cataclysm heroic dungeons like Vortex Pinacle or Throne of Tides?Becuase 85 HC dungeons are not soloable by most clases (i'm druid and i can solo only Stonecore normal etc.
Still worth it even nowadays. Helped tremendously
You can buy everything on the AH for fairly cheap prices so it's better to go that route considering how you can't get trophies from higher/max level dungeons and raids.
