Yes using this instead of a goblin footprint would be nice. But I want to know if anyone thinks there is any sort of problems with being able to enter a past event instance. Say if someone wanted to talk to Alfgar NPC who has been spawning in ul'dah randomly. I still havn't been able to catch him. After event ends I could just access my echo and use it to travel back in time to a small instance area where I could talk to him.
