Once I had to get the last part of the collection "The Convergence of Sorrow II: Requiem", which is going to Jahai Bluffs. And I was very bored. All the achievements of this zone were completed, but "Death-Branded Shatterer" event did not start. And I thought that I was really missing something to do while waiting for the event. It would be very cool if some collections were added in all zones, like this is done in Rift, Everquest, etc. I very liked this mechanic. In GW2, there are a huge number of secret and hidden places in all zones where could hide (randomly generated) parts of collections. And yet, why not introduce the legendary appearance of mounts? With a very complex mechanics of receipt. Yes, I understand-the store, gems etc…But I think it would be interesting to introduce such an activity.
