Same, I want Vader to defeat someone extremely powerful to cement his strength. Vos and Ventress seem to be a good duo for him to test his skills.
You make it sound like this is pro wrestling.
He's DARTH VADER. He won exactly ONE fight in the OT (and barely that, since Luke succeeded in getting away). He was still Darth Vader.
He doesn't need wins over preliminary talent to prove he's Darth Vader. He's DARTH VADER.
