Doing a quick scan from Burning Crusade through MoP, I can see Tier Token tooltips from all raids except the Cataclysm T11 and T12 raids, though Dragonsoul (T13) tokens work fine.

Example from Dragonsoul:

Example from Firelands:

If I'm reading it correctly, T11 and T12 tokens are Class: Quest Items - Armor Token (which matches T4-T10)
Dragonsoul, which works, is Class: Quest Items - Junk (This one seems unique. After T13 it's Class: Miscellaneous instead of "...Junk")

These ones are problematic mostly because there's terrible information on what they'll actually give you. Note the "currency for" tab on Chest of the Corrupted Protector versus Helm of the Fiery Protector.

It looks like the wiki does have the outputs (well, it has the original vendor data, but we can probably assume those are the items the new right-click behavior will create), but that's an annoying level of manual data-extraction from those pages to be done.

On investigation, most of them are actually there -- it's the Helm/Mantle tokens on each tier that're missing.

I've added those missing ones into LibArmorToken. I'll try to get the ones in #23 as well, and I'll do a release once that's ready.

Thank you so much for your work on this addon. I just came across it recently, as the Tier tokens are now account bound, and as a transmog enthusiast, I'm in love with it. Super helpful!
