I checked the market (EU server) prior to shutdown and saw all glyphs posted in a range of 6-15g, which was at best a 100% increase. As many stated here already, most will have stacked up what they need and/or have a friendly guild inscriptor to help filling the gaps. There always will be those few with the "idc"-attitude and for those I just applaud all scribes to finally make some money out of their profession. As the OP said "The glyph market is on fire" - but it will be a straw fire, no doubt.
