Guild Wars 2

At first: why does it disappear?
Also, what about people (and I personally know a dozen of such) who still keep dragon’s jage tickets? Because developers, as I know, want to redo all the currency onto the black lion. I bet people have spent a lot of time and money to get the dragon’s tickets. Will devs compensate it to them? Otherwise I foresee oceans of indignation.

They have not disappeared. If you have a ticket you can still purchase or preview them from the vendor.

If you don’t have a ticket you can look on the Trading Post.

nope, they’re still there. There’s a new option saying “I have one of the limited time claim tickets” on the merchant. You gave me a mini heart attack man!

The Weapons trader that takes in Tickets for Jade, Fused, Wintersday, Zodiac weapons etc is located up the stairs by the Black Lion Trading Post. They’re also tradeable via TP now too.
