There's nothing wrong with some piece of glamour being rare and taking some time/resources to earn. I'd be thrilled if they kept aquapolis relevant by keeping some rare items/glamours obtainable from there only.

But I'm pretty sure that whatever the new PotD thing is they've got planned will have pieces of old world and wool tops dropping like penny candy, much like Thavnairian and moonfire gear did, and make all of it absolutely worthless.
