I doubt that any flesh and blood force user can "easily" beat him. He was able to fight the combined power of Ragnos + Tavion at 14, and as a 40+ year old was able to withstand the force crush of an ancient force entity.
So no, I don't see any humanoid force user having any kind of "easy" time with Korr. He's somewhere at Kyp level in the force, and he has Mara and Kyle's skill and tenacity in fights, I'd actually make him favorite against an aging Palps or Luke.
Ragnos was a spirit, he wasn't "weakened" anywhere - any sources that say he was weak? We already saw what a younger Exar Kun spirit did. Tavion was hardly featless with the scepter she was above Katarn and Korr - Vjun. And she had more power left over to empower normies to become force sensitive, not to mention empowering the whole Reborn faction. She had also siphoned dark side energy from several worlds.

Nah. Ragnos was a weakened spirit possessing some featless Tavion. Korr literally has no feats putting him anywhere near the level of Luke and Sidious, or even the likes of Dooku.
Luke and Sidious are hardly the be all end all, as far as force users go, they were kind of geeks. More bookish, less natural warriors.
