Really? It said it was based on sword fighting. Anyway, I wasn't referring to mastering it. I was referring to basic skill(I.E. knowing how to use it without stabbing yourself.)
Here's what part of the article said- Lightsaber combat was the preferred method of fighting used by the Jedi and Sith, which was initially based on ancient sword-fighting techniques. All seven traditional lightsaber forms included the same basic techniques as ancient sword-fighting styles, such as defensive postures, overhand strikes, parries, and counterstrikes.
Plus, Non force users could use it effectively.(Grievous, Proxy)
Grievous was a cyborg, and Proxy was designed to lightsaber duel.
