I sure do wish any of this shit wouldn't just go away when the expansion ends.
These are just glyphs with a fancy UI which, while welcome, will inevitably boil down to wanting a particular one for your character. This also just feels like what everyone was asking the Heart of Azeroth to be to begin with, so it leaves a bitter taste in my mouth that they went with that shortsighted first idea and then went "Ooops! I guess it turns out that didn't work out!" No shit it didn't, players including myself were expressing our concerns since beta with the system's design.
In general I just wish there was more to our characters on a fundamental level rather than all this useless expansion fluff piled on to a bland and forgettable base. If you're going to bring glyphs back, why not just...you know, not fucking remove glyphs?
