I couldn't agree more with you
@Drakelord . The TMap revamp introduced several cool things like the ancient weapon or octopus necklace but I feel like it was only half implemented because once you have these items, there is nothing to actually do with them (other than decoration). They also don't have turn-in points (for trash) so it's really not even worth taking them out of the chest.
I think they should be part of a quest where someone is looking for these items and when returned you are given a reward. Personally I think the reward should be something like a random no-name legendary item. Something along the the lines of "oh good you found the ancient weapon I need for my collection! Here I'll trade you this item that I found along my travels that I have no need for.".
