I was on Wowhead looking at some of their coverage of Warlords since MMO-C has slowed down a bit, and they had posted a bunch of data mined icons, beyond those that were posted here. Additionally they separated the icons into categories.
Under the Armor and Weapons section, there was a subcategory titled LFR, and one titled Raid. The LFR category had a series of icons that belonged to sets, however by the look of some pieces like shoulders, it is unlikely a tier set. It may just be a different set, like how Mogushun Vaults dropped a seperate non-tier raid set from Heart of Fear and Terrace of Endless Springs, but the fact that the icons are labeled along the lines of inv_plate_draenorlfr_c_01pant suggests it may not be as such. In the subcategory titled Raid, there are only icons for necklaces. The icons are labeled along the lines of inv_6.0raid_necklace_4c. Not only does the raid icon have a patch next to it, but it is labeled as raid, not LFR. The LFR piece has no patch next to it, and is labeled as a LFR piece, not a raid piece. Trinkets are in a separate subcategory, along with a section titled other that may have weapons for LFR.
Now, because it is early I'm not surprised to not see tier icons, since they dont want to spoil what the tier sets are, or they haven't designed them yet. However, the gear labeled as LFR seems very simplistic and is not marked as a specific patch. If we would have a set of armor like in MSV that was not tier, but a raid set still, I think the armor would be under the raid section, and not labeled explicitly with LFR, and probably be labeled for 6.0
Blizzard has wanted for LFR to feel less mandatory for gearing up or maximizing gear, but tier/trinkets have still been a common complaint among players doing higher modes. Prior to the nerf, LFR UVLS was still one of the best trinkets for Demonology Warlocks, surpassing Heroic Warforged trinkets because of how strong the proc was. There was some speculation of LFR being further downplayed when they made the "tourist mode" comment, but they hadn't said anything about it since.
Is it possible that LFR going to not drop raid sets in Warlords, and instead just a separate set of gear, potentially through the entire expansion, maybe just changing the stats?
