Who were THE masters of lightsaber combat??
Which characters were considered to be THE greatest masters of each form of lightsaber combat??
*only one character for each form please.
And a side question: if each of those masters were to fight in an arena setting, who would win if it were strict lightsabers only combat?
Kit Fisto and Lucien Draay are the only notable Form I practitioners that come to mind.
Dooku for Form II.
Obi-Wan for Form III.
Yoda for Form IV.
Anakin for Form V.
There's no particularly standout Form VI practitioners. Revan is the closest thing. If you subscribe to the idea that Sidious was a Form VI main, then it's him, but there's no confirmation that that's the case.
Mace for Form VII.
& obviously Anakin would steamroll the rest.
