Thanks for raising this issue OP. At the moment I have 3 beast tribe currencies, crafting and gathering tokens and the unidentifiable items for the relic all taking up room in my bags. It makes gathering and crafting a pain, because I'm constantly shuffling items between my character and her retainers. I have sold stuff to make room but often find I need it and have to buy or gather it again. In other words, I could really use the slots these items are taking up.
What''s really annoying is my 'key items' tab is mostly empty. Even doing the hunts and treasure maps, I don't think I've ever filled up more than two lines of it.
