I preferred when buying glyphs actually made a difference; mainly in PVE I admit. Seems like all the glyphs these days are more or less for PVP, which is fine for PVP ofc (options are always nice), but otherwise glyphs seem very lacklustre. Of course there some classes and specs that have a few important/necessary glyphs, but seems in general they borderline irrelevant; I could raid with my DK without any glyphs basically.
Now, I have Inscription on an alt, which I intend to drop for Mining since I'm not interested in trying to make money with Ins, so my point ain't either to whine about getting gold. Despite the glyphs having being more or less set in stone for what you used to need for raiding/maxing your dps/hps/mitigation, at least I got the feeling that I was improving my character. I don't mind the visual changes the minor ones provide, but the major glyphs seem bit of letdown most of the time.
Feel free to agree/disgree, at least try to make vague attempt at being civil
