problem with that is, about the time of the event, all the english districts fill up completely. so you'll get a flood of new guys who might want to support dwayna :P
For anyone on teh euro districts, 15 and 33 have been grenth the last 2 times, and you can get one character to 15 and then as soon as you have them get another to 33 and get some more.
As for international no one has a clue when/if they will arrive.
Having just experienced the Wintersday finale, I feel something needs to be done about the reception of Yule Caps and Horns of Grenth.
What we need to decide upon, as those who wanted Horns of Grenth did, is a district or five dedicated to a particular avatar, so you can be sure to get the headgear you want. I suggest even districts for Dwayna, odd districts for Grenth, or something like that.
I say this only because there were so many people going "Grenth FTW!" or "All come over to Dwayna please". I even saw a few people say that their avatar gave out ectos to those near them. o_O
A little organisation on the part of the players would be nice, seeing as ANet has given us a choice.
