My list of Glyths that I can purchase currently looks like this Angry thoughts (115) Arcane Secrets (115) Destruction (110 - 114) Dragon Scales (115) Not sure if my Destruction got bugged as I had one ready to use when I leveled. Currently have a button which says unusable and a purchase button which is greyed out.
Glyph You have to level it the same as you did at 110. You have the 40? AA to purchase to level it to the 115? Are you 115?
I'm level 115, I used hundreds of them when I was level 110. I have over 40 to purchase it. It is the only one which is listed as 110 - 114 the others I haven't used for years and they are fine and listed at 115.
