@formally_darth: Yeah it's pretty obvious. Vader only holds a "slight" edge on ESB Luke, a rookie with only a few days training and is inferior to ANH Kenobi. Even Pablo Hidalgo has said that RotJ Luke is "not very powerful of a Jedi" despite him being equal to Vader.
Then you have George stating that Vader is inferior to all the "golden age" Jedi. Of which even even TPM Kenobi is one of the best and that even as of ESB he's lost a lot of power compared to his RotS self. Then Pablo saying he's lost a lot of power compared to his AotC self.
like another Member just said...you can't scale from Multiple difference authors with just statements.
If he was so weak like you are claiming he is, how was he able to kill so Many Jedi? Sidious Even called Vader the Best Jedi Killer Ever. how is he weaker than TPM Obi-wan when he one-shotted TPM Maul? you don't make any type of sense in here.
