Rat is a great ride and worth a fast pass is it tier 1 probably more so then Frozen for ride quality. I enjoyed it in Paris this year as for Mary Poppins, I dont think we know enough about it to make that decision. Epcot is also a different beast though than Hollywood Studios, for some of us, Epcot is less about the rides and more about the festivals and experiences. Im not talking about drinking around the world here. I suspect Guardians of the Galaxy will also be a teir 1. As for the rest of the rides. I could see the need to actually make either soarin or test track a teir 2 after the rest of Epcot is done being reimagined. This would be a few years off but Soarin in itself has multiple theaters and its show building is pretty empty and could easily be a people eater once newer attractions are available. I know not everyone might agree but give it time if they keep the fast pass system as it is, I really think it could be a inevitable tier 2
