Is it true that there weren't but 15 people that attended that meeting??? If so, it's sad that all this hullabaloo is just to keep from hurting 15 peoples feelings. Just sell the damned thing in the store and be done with it, no replica tag needed. I got one, I'm not worried about it's value going down...had I got it from the meeting, I would still have the memories of the day. So sell it, well, whenever they get those mysterious delivery problems solved.
Not sure about the later events that gave out the robes in games, but I can speak for the original event that was done in real life.
There were about 70-100 non-EA people at the 15th anniversary party at Fairfax, many of which were invited by the EMs of the time.
Typically, 2-5 people who were the most active in the RP aspect of EM events, and/or ran their own player-ran events, got invites on each shard. After the RSVPs, the Mythic staff chose people from those who emailed them about wanting to attend. Unlike most events/town halls, they needed to know as close to the actual number attending, as they had to make sure they had seating & parking, had enough food, and wouldn't anger the other building tenants or the fire marshal.
About 4-6 of us were from Stratics - and half of us were there not because of Stratics, but because of our activity on our shard during events. They even forgot to announce me and the guy I rode in with as being from Stratics, because the Stratics officers at the time that did attend (and presented the staff with a plaque or something), somehow repeatedly missed our telling them we'd be there.
Most non-Asian shards were represented (if not all; can't remember if both Europa and Drach were represented, or if someone from Oceania made it). There were many people from the eastern US shards, not so many for the western ones. (I was the only Lake Austin person that attended, as far as I know - and that was because I came from Kentucky).
On what was effectively a coin flip, one side of the audience got TWO sets of codes for robes, singing balls and combination chests, because they had enough card sets in case everyone invited showed, and only about 2/3 were able to.
When they did the event, they were juggling an in-game event and an in-person event at the SAME TIME.
My particular robe will never be sold, and as far as know, I never heard who - if anyone - won a robe on LA (for the story event), so at best they would be extremely rare on my home shard. Past experience is that too many things that get awarded/handed out on LA don't stay there.
I have always wanted the design to be available for others... But the name should be appropriate to distinguish between the originals and the later iterations.
