If I as in charge of Epcot, this is what I'd do. I know that most of this would cost a lot of money, but here's my take on restoring EPCOT...
Futureworld pavillions:
-Mission: SPACE
-Test Track (major renovations to outside of building, make attraction more "futuristic")
-The Seas (remove the Nemo branding from the name, make more "futuristic")
-The Land (fix the escalator problems and renovate boat tour)
-Spaceship Earth (remove LAL and move tiles to structures inside Innoventions, add new logo to mirror support, improve the wait line)
-Horizons (maybe "New Horizons", new building similar to original to replace WOL)
-Imagination! (restoration to classic or major renovation)
-Universe of Energy (slight renovations)
-Innoventions (make building look more "futuristic")
I think that Futureworld needs the most attention and World Showcase could be put on hold for a while.
