I just recieved this ingame mail:
The Guild Wars 2 Team
Thank You!
Because you purchased gems through our Gem Store or via a Guild Wars 2 Gem Card between the launch of Guild Wars 2 and June 9, 2013, please enjoy the attached gift from ArenaNet. These minis are available in the Gem Store for a limited time to celebrate Dragon Bash but we wanted you to have a set for free. We really appreciate your continued support!
Attached was a Dragon Bash Mini Pack. In the pack was:
Mini Holographic Branded Minotaur
Mini Holographic Axe-Wielding Destroyer
Mini Holographic Corrupted Wolf
I tell you, I feel positively spoiled by this company
