My Retribution Gear Set so Far...
Neck: Chained Military Gorget (Using my Tanking Neck piece)
Ring 2: Stained Glass Shard Ring -
Trinket 1: Incisor Fragment
Trinket 2: Mirror of Truth
Libram Slot: Libram of Furious Blows
So far it seems decent to raid with and do decent dps when switching to dual spec for guild raids or just whenever playing around on quest or whatever. I can spend spend money just for a Neck piece but I just rather use my tanking neck piece for now since it has decent stats and hit rating on it. Being a tank and dual spec as Ret I don't have any priority for gear upgrades in raids and I'm not counting on picking up much since guild have lots of melee dps and dps plate as well. And I guess its not much a priority to focus on quickly improving my Ret gear over my tanking gear set(s). May have to run a few guild 10 mans as dps maybe for any upgrade but not sure how much upgrades can possible get in 10 mans other than tier pieces maybe.
If I pickup upgrades from raiding them I guess that will just be fine I guess. A Libram upgrade I'm sure I can pickup on a next Naxx raid hopefully as I'm not going to spend Emblems of Valor to pick up dual spec gear over tanking gear pieces. But at least I did put some work into the gear to make it decent for raiding utility and can provide some utility when needed as a option. But that's my gear I had together after the patch went live. But WTB more bag space, with all that gear in my bag I barely have any free space.
If you know of good gear upgrades to above do let me know. PvP is out since I don't PvP. I may have to dps a few VoA to maybe see what comes up as well and with the Argent Tournament for weapons which I'm already working on.
