It's not EPCOT... but someone posted a pic of signage at Hollywood Studios that showed availability of Fastpasses. It showed Toy Story, Rockin Rollercoaster, and Tower of Terror as "limited" and then every other attraction (rides and shows) at the park had "AVAILABLE" next to it.
That's the absurdity of tiering... no one wants to bother using a FP+ to see Indiana Jones, Little Mermaid, Muppets 3D. Just like no one at EPCOT wants to burn a FP+ to ride Spaceship Earth or Finding Nemo.
They're simply not necessary.
