Here's the thing, as someone who's worked in film, theme park design, and literal illusory magic: it doesn't matter how tough it is to pull off an illusion (and good stunts qualify, in my opinion). All that matters is the visible result and how the audience perceives it. The hand-to-hand combat might be some of the most challenging ever pulled off in a recurring, live setting, but if it doesn't read as impressive to an audience, does it matter?
