No shit he'd get wasted by the absolute top tiers of the genre lmfao. He obviously doesn't have their training, hasn't shown any of their power in the force, and he hasn't even been on the screen for more than one film. We obviously know very little about his abilities, so its ****ing hilarious to compare him to juggernaut Sith like Vader and Maul.
If anything he should be close being the force feats we've seen from him, and being apart of Anakin's bloodline. If you're judging his performance by one film when he was injured and was facing an opponent of (possibly) greater force potential, than you may as well shit on Luke for losing his hand and being toyed with by Vader in Empire strikes back
