Yes, obviously I know you can buy the upgrade from the vendor in Tanaan as it is the only upgrade I can get my hands on as I don't get in raids.
It is the upgrade from that NPC I have used to upgrade to the 762 ilvl I have now. So a lot of boring LFR runs :P
As I said... I don't raid, so I don't do mythic dungeons either. From what I can see you need achievements for everything and high ilvl(I have like 706 or so). That's how it is on my realm atleast and what I can see in LFG groups.
So I have daily dungeon + LFR + weekly event some weeks(pet battles next week, so no valor and I don't do mythic dungeons week either).

Yes, I'm a wood completionist with a low functioning brain, you all mighty pro player
Edit:
My point isn't really that I have to complete it or I will start crying, but that I don't see any reason to remove a grind for an item that will not be used in Legion. It's not like people would hold on leveling when Legion comes until they have farmed valor for the first few weeks just so they could completely upgrade their ring because they would refuse to level with a ring that isn't fully upgraded - and I don't think anyone would really care if someone else would be able to fully upgrade their ring or not.
