Anet spends time making the masks ect then throws a HUGE party for them with like minigames and quests and items to get, then everyone forgets about them as soon as they got them.
I really like the idea, i think the prices are right and the idea is just waiting to be used.
The only thing i think should change is that they should only be made available to level 20 chars. Sure, you could put low AL ones in the erlier cities and then progressivly raise the AL as you progress through the game BUT if you place the max ones in Consulate Docks, Kaineng Center and Droknars Forge, you would end up with level 1s running around with them. Those cities are easy to get runs to (minus Kaineng, im not sure you can get a run there) so you would have low-level characters getting them.
If you make it so you can only get them as of level 20 however you loose that.
Just my thoughts

i think its a great idea though

EDIT: If you think about it, the masks are already common and the property (or whatever its called :P) to make the EoTN masks common MUST have been based in some way on this.
All anet needs to do really is just make them have insigna slots and +1 to items attribute on them with a trader ect and then its done...
This shouldnt be hard AT ALL to implement...
Dout theyll do it though
