So Turgaroth hit lvl50 some time ago and with trial and error I tried to figure out how to get him geared up for hardmode instances. Appearantly you can't just run any HM instance without the proper gear. What you have to do is run DAILIES to get Commendations for legendary equipment.
Anyway here are two links with further explanation:
