Everyone wants to see Luke being a badass in the sequel trilogy,
Legends Luke was too OP and flies in the nature of the movie character, IMO. TLJ was a much more plausible Luke, but that’s a discussion for another day. Being a badass doesn’t always mean it’ll be a good and complex character.
What do you mean by plausible? Everything is made up either way. It’s more about what is satisfying.
