I'm just waiting for an update in a future patch where the glamour dresser no longer destroys the gear you glam, and the ensuing rage.
I don't think anything was mentioned about this new system overwriting current glamours, so it took me by surprise. I was ready to nuke one set despite being 60 4-star gear I crafted, but I'll be damned if I nuke my raid drops.
Looks like for the time being, I'll be sitting out with this new feature until it's improved
