That’s the only blue post I’m aware of about S4 gear. Nothing about rating requirements being removed or points being added at a different time than any other week.
edit: My mistake, there was another - rather unclear- snippet reply in the EU side of things. https://eu.forums.blizzard.com/en/wow/en/wow/t/burning-crusade-classic-season-4-ends-august-30/376198/18
So rating maybe should be gone, but in all honesty you’re better off waiting for the honor conversion + discount anyway.
