It was, at the time. And for quite a while depending on the class.
I shall die here. Every inch of me shall perish. Every inch, but one. An inch. It is small and it is fragile and it is the only thing in the world worth having. We must never lose it or give it away. We must never let them take it from us.
To be honest I'm going to put my glyphs up on the AH for around 120g. You want them forever? You pay the price. If scribes have the glyphs you need and they are ONE-TIME to buy and then you have them forever. I believe glyphs will be put up on the AH for over 100g at least.
Yeah, if you have a scribe who floods the market with 2.5G glyphs for half a year now, that might change your plans. My guess that he makes just enough profit or goldcapped already to not care about it. And to be honest 2.5G is still profitable.
