Just to clarify. The main reason Yoda was amazing with the lightsaber was because of the force.
"Much of his lightsaber combat style relied on jumps and acrobatics, many of which were aided by the Force and augmented by his mastery of Force Valour." - starwars.wikia.com
So even though he used his lightsaber, the majority of his fighting was done with the force. As a side note, Yoda was trained as a Jedi Consular.
Edit: This is also a game. If you don't like the class, don't play it. If you don't like the game because it isn't hand catered to you, don't play it. This isn't WoW, quit whining on the forums like it is.
