That items tell you were they can be exchanged / which NPC is involved.
Sometimes you get token and you need to go to RadzatHan, sometimes Eulmore, Idylshire, Mor Dhona, Kugane... it's messy
Wish there was more clarity there or that they revamped token trading as a whole.

in the same line, I just wish they revamped tokens / upgrading gear with tokens as a whole... so messy...
Get two coins, change the 2 coins for a token with a NPC. Go to another NPC to upgrade but you can't have that gear equipped so switch job before your talk to the NPC, then select the gear and the token....
Why so cumbersome?
