Just finished 100% (all hearts, PoIs, skill challenges, vistas for world, cities and all WvWvW maps). Last point was a vista in WvWvW. I do not have all of the smaller explorer achievements like Krytan explorer (as I understand they are not required).
What worked:
- Got title “Been there, done that”
- Achievements show 100% world completion
- Character select screen shows 100% medal
- Received standard map completion chest
What did not work:
- No gifts of exploration
- No ingame e-mail (not even for map completion!)
- No star above my character according to other players
Me sad panda!
