More (for, the lack of edit feature) on the LOE page:
pg.251: Aged, experienced, diplomatic, informative, brilliant with a lightsaber...Yes, all of these things. And not unacquainted with the power of the dark side. At some point during his 900 years, Yoda may have dabbled in the dark side of the Force.
Qualified by "may" but it may also mean he encountered somebody who used the Dark Side of the Force (ex: Palpatine says "now you will experience the full power of the Dark Side of the Force," but that meant he was going to zap him, not train him!).
pg.186: In midflight from the vibrating blade, Obi-Wan watched Anakin rid the Falleen of blaster and hand, and thrust his lightsaber directly into the Falleen's chest. Whatever torso armor the humanoid was wearing beneath his jacket gave the energy blade pause, but heat from the lightsaber set fire to the Falleen's bandolier of explosive rounds. Personal armor slowing a stabbing attack by a lightsaber
Compare to Yoda tossing a lightsaber blade casually through the chest of a Trooper in ROTS. Granted, the armor may be different, but surely this "Falleen"'s armor isn't superior to that of the Republic's shock troops? Granted, it's Yoda we're talking about here...
Nitpicking, but still. Nice set of quotes!
