Honestly Blizzard if you won't budge on account wide essences, can you budge on alternate ways to earn essences, ones that are more relevant?

I'm thinking in 8.3 Corrupted Mementos you earn from Visions of N'Zoth are a great way to piggyback Essence and Rank Essence acquisition. It means you don't have to go to patch old content like Nazjatar and Mechagon reps while everyone is enjoying the latest 8.3 stuff. It also creates an alternate grind that lets people have options in case their essences are too grindy or just in content that isn't fun. They can also make say, killing N'Zoth give some Corrupted Mementos or killing N'Zoth week by week another shot at getting an essence.Keeping your players in the same patch is a pretty good goal.
