He managed to challenge Vader
The same Vader that tooled Luke in five seconds when he really got pissed? I hardly consider it a "challenge", I call it pwnage.
Anakin challenged Dooku, who was a much more impressive swordsman.
who is an amplified Anakin only six months form his maxi-potentialization when he killz00rs the Emperor
Can you explain this? Cuz I don't know what you're trying to say here.
And of course, Luke would have been a lot faster, but choreography in the 70's and 80's was lacking.
More of this "OT characters pwn cuz the choreographies sucked?" Please, Luke is relatively inexperienced and untrained, how could he possibly become a master swordsman overnight when it usually takes Jedi decades of training to even become a Jedi Knight?
