This is a bit of a specific one.
As an arms warrior I used to be able to use Recklessness. (Like Cata or something, I am not sure, I don’t remember) - At this time I had the Glyph of the Weaponmaster to change the appearance of my weapon whenever Recklessness was used. At the time you couldn’t transmog say a two handed axe into a two handed sword so this was a solution for said issue.
Over time things have changed.
Recklessness is now no longer available to arms warriors. However the glyph is still applied while in this spec. (I can even look in my spell book and see it glyphed under the fury tab). But when I take the talent Warlord’s Torment, it causes a few skills to trigger Recklessness, which in turn triggers the glyph.
While this isn’t a big deal it is very annoying.
It is impossible to remove the glyph. I have tried a wide range of really silly things with vanishing powder while doing other things to hopefully get the glyph to go away. But no such luck.
I opened a GM ticket and after WEEKS of a very slow back and forth between a few GMs that thought I didn’t understand how to remove glyphs, they gave up and said maybe I could make a forum post.
So here it is. The bug report. Please make glyphs removeable on all spell book tabs, not just the active ones.
