Well Firstly I'm gonna have to say the new badge ring (60 badges) is a must get
After that I would like to know if you are actually raiding T5 content atm because I can't see any of the gear that drops there on your armory page ?
If you do .....then the T5 Shoulders and Gloves would help your gear appreciatively imo . From trash in TK the Seventh Ring of the Tirisfallen is a nice ring to have if you want to combine a threat based setup ( nice SBV ) and the Bracers from VR are allso nice to use in combo gear for extra mitigation . The Mallet of the Tides from Lurker is allso the best tanking weapon in game before BT
On badges after the ring ... I would get the GAB trinket and the Brooch of Deftness Neck .
From ZA the boots and Head and then you should be set to start MT all T5 content and most probably be good to start T6.
Atm I would say MT T5, OT T6 and if you have good healers MT ZA
Hope this helps
