Guild Wars 2

I tried digging into the patch notes to see if I could find it but I can’t.
Apparently the trait “Inscription” doesn’t lower the cooldown of this glyph. As far as I remember it did and it was on a 20 second cooldown but it does not.
I tested it out and only the heal glyph is the one not affected, other glyphs are just fine. Was this a change a while ago? Is it a bug?

There is a recent thread about this
