I think the scoop ride is the best option for a big Avengers attraction and it doesn't matter if Universal used that technology before. When a park builds a new rollercoaster nobody complains that there are already rollercoasters in other parks and the same happens with new dark rides, water rides, flat rides, parades, drone shows, etc.
The scoop ride has proven to be a success that lasts in time, and the new Peter Pan version in Tokyo looks amazing, so I'm happy that this kind of attraction is becoming more common.
