Weekly chest only drops items from the highest key's dungeon you've completed?
Someone said that there was a blue post, explaining a hotfix where the weekly chest now only drops items from that said highest dungeon you've completed.
Say you've completed a DHT +16, you only get items from DHT.
I'm 99% sure that they either mis-said something or you mis-heard. The only thing (that I know of) that's changing with the weekly cache from M+ is that they're adding AP, and that AP is scaling with your highest + for the week.
Otherwise, if I'm wrong, I'd love to see a link to it as well.
