{future} release Brutal at the same time
I know plenty of people, myself included, unfortunately displeased with "Glamour Tower" not qualifying as 'legitimate' end-game content.
People deep in the Second Coil have practically no purpose for CT2. Sands & Oils are a good step but they aren't even being included for a while. Further reducing CT2's usefulness for active raiders.
Ofc, this will require 24-man queuing or it'd be a disaster. But I think this the right approach for the future.
As well, it should have the same gear rewards but in different colors to distinguish them, in addition to the achievement title.
Even better, if Brutal's receive an ilvl sync so they're utterly skill-based for the challenge aspect.
