I would say that coaster thrill rankings are something like:
1. Very small kiddie coasters
2. Family coasters such as Hippogrif and 7 Dwarfs Mine Train
3. Moderate thrill family coasters such as Space Mountain and Cobra's Curse
4. Thrill coasters such as Expedition Everest, Cheetah Hunt, Rock 'n' Roller Coaster, and Verbolten above.
5. "Extreme" coasters such as the big B&Ms and Intamins like Hulk, Manta, Maverick at Cedar Point. Stuff that pulls consistent strong physical forces and a lot of maneuvers.
I'm guessing the new Potter coaster will be somewhere in the 3-4 range. Which is fine.
I'm sure it will be more immersive. I was referring to the design of the coaster and ride system and the fact that it has a drop track section, which is rumored.
