LeGenD, this is a deeply misleading account of the situation involving Master Yoda's attempts to handle Darth Sidious's Force lightning. I'll respectfully ask you that, if you can't debate this objectively, don't bother debating it at all. It becomes tedious and annoying when I have to come here and correct you.
What about the second Force Lightning attack that Yoda tried to block but it resulted in the blast that send him crashing in to the senate floor.
Absolutely misleading and grossly incorrect. Yoda did succeed in staving away Emperor Palpatine's Force lightning -- the only thing that he failed to do was to protect himself from the ensuing explosion when the lightning coil released itself -- but one must take into account that Palpatine himself couldn't even withstand the blast, and he was the one generating it.
After that Yoda gave up.
...And you blame him for it? He was without his lightsaber against an opponent who was his equal in Force prowess and mastery, and to top it off -- he was in the heart of enemy territory relying on defensive techniques to come close to victory. It's a no-brainer that he left, because the odds are, if he continued the duel, he would have died. Yoda is willing to die for his cause, but the cause here demanded that the Emperor must also die. That wasn't going to happen, so he made a tactical retreat; a decision that later benefited his attempts to overthrow the Empire completely.
So indirectly, Force Lightning attack forced him to change his mind.
No.
A logical assessment of the situation (detailed above) is what 'forced' him to change his mind.
-The first Force Lightning attack stunned and overwhelmed him.
Excuse me? This is a very primitive assessment of the situation, LeGenD. Master Yoda entered Palpatine's office there on the full strength of his convictions; that is to say that he went into the fight a trifle too cocky and arrogant. He was sure he was going to win. While he certainly paid the price for his arrogance with the subsequent blast of lightning, to say that Yoda -- for whatever reason -- was just overpowered and rendered unconscious would be false. He was caught off guard (though I grant you that the move itself wasn't surprising), and when he attempted to subdue the lightning -- too late -- it then overpowered him.
But that isn't to say that if Yoda had been prepared, wary of attack, he couldn't have defended himself. Logic points to the fact that he would have.
-The second Force Lightning attack resulted in a blast that send him crashing on the senate floor.
This is a lie.
When the Emperor attacked Yoda with Force lightning that final time, Yoda did hold it at bay. What he did not (nor what the Emperor himself did not) defend against was the ensuing explosion when the coiled lightning released itself. There is a difference.
So in both cases of Force Lightning attack, Yoda faced humiliation.
In the first one? Yes, but only because of pride, not lack of ability. In the second? No. There's nothing that he could have done to have changed the scenario.
He might have learned to perform an FLS as well.
Those attacks weren't storms of Force lightning. Palpatine was just powerful enough to do all that without going apeshit and turning into Captain Lightning.
That is not surprising, considering the lethality of Force Lightning and Palapatine’s proficiency in it. But this is invalid. I am not talking about Palpatine’s proficiency in Force Lightning. I was saying that FLS is far more lethal then the Force Lightning that Palpatine displayed in his fight against Yoda in ROTS.
Proof? And, furthermore, prove to me that a storm of Force lightning isn't just out of control Force lightning and not a separate attack entirely?
Considering the fact that FLS is pinnacle of Force Lightning, it would be impossible to defend against it as a living organism.
Prove it.
That is already given. We are talking about DLOTS incarnation of Revan.
...Who is weaker than any incarnation of Palpatine, and subsequently, Yoda himself.
