Chest is from Naxx (Grob/Faerlina) and Malygos and legs are from the first boss in Drak'tharon Normal.
I never really cared for the weapons tbh :P I'm not a soldier, some randomness is desired
Updated version, with chest from Hyjal's 2nd boss. Need to change the belt to PvE version tho', it has nice effect on it and blends better
