I think that most of us already know, but this uncraftable sigil has been acquiring a very high value since the release of the patch due to the upgradeable Armor requirements.

Will it be changed? Will we have a recipe? Is ArenaNet taking any actions toward it's availability? It would be a shame that this armor, which is a main content of this patch, would be so highly expensive when other times it was not the case ( like the Luminescent armors ).
