I feel like Saviors of Uldum could be in the 'Missed Potential' category. They could have made it sooo much more interesting. But it ended up being somewhat of a dismal effort in the end. Delving further into the Egyptian theme would have made it a lot more interesting.
Before this next expansion, I decided to list my most anticipated expansions to least.
This regards only the theming of each expansion like lore, trailer, and mechanics introduced (w/o gameplay). Left most is the best in each tier.
Feel free to make your own below!

I would definitely put Kobolds higher since its Dungeon Run had me hooked.
