I decided that I like the look of the new legendary focus enough to do the quest to craft it. However, I cannot unlock any collection. I talked to Hobbs and he knows nothing about that legendary focus, he even gave me a smile that made me feel stupid for even asking. I asked in LA map chat, nobody knew, I asked in the Mistlock Observatory where I've seen a couple of people with the focus in the last weeks, but nobody knew.
gw2efficiency tells me the ingredients, wiki and dulfy give no hint how to start the journey.
So what's the trick here? I have HoT and PoF and finished all stories.
