Depends on the fight actually. I changed glyphs sometimes in ICC this week.1) How often do you think people will be changing glyphs?
As a scribe, I agree with this change, I just don't understand where they're going in Cat when there are no new cataclysm glyphs. I made an absolutely obscene amount of money off the old glyph system, it was really quite ridiculous.
Granted I'll probably drop inscription now and put it on an alt since I won't need to make glyphs for myself anymore.
Yeah I made a killing from buying Enchanted thread (I think that was what it was called, it was required for low level LW and Tailor proffs.) at 89s from vendors and selling em for 2g, it may not sound much, but high volume added up to a killing.
Many things that can be sold by vendors just simply aren't known that they are.
