It's worth remembering that COP has one of (if not
the) highest hourly capacities of anything in Walt Disney World, including famously high-capacity experiences like boat rides, omnimovers, and the resort transportation system. It's one of the few (only?) attractions that has adequate capacity for every visitor to the park to be able to experience it during a typical day of operations.
Even running at only 50% utilization (which, granted, does not happen very often), it still has a higher hourly throughput than recent headliners like Flight of Passage, 7 Dwarfs Mine Train, or Tron.
The short wait isn't a flaw: it's a feature, one that was central to its inception.
