These types of discussions are always funny because of the rationalizations that people allow their minds to run with, like the old Batman vs. any other super hero that has super powers. I am about to share an actual conversation I witnessed between a Robert Jordan fan and a Mistborn fan regarding Lan vs. the most powerfull Mistborn ever.
MBF: "By the time you even think to reach for your sword, I'll have iron-pushed on it and sliced you in half."
RJF: "Too bad I didn't even bring my sword to the fight 'cause I knew I would not even need it."
MBF: "Ok, I'll just shoot this coin through your skull and then sip some lemonade."
RJF: "Gotta find me first. I have my fancloth cape on and am completely invisible."
MBF: "As the most powerfull Mistborn ever, I can see the trace metals in your body; I know exactly where you are."
RJF: "Unfortunately I had a mouth full of metal powder and spit it into the air, forming a big cloud, effectively blinding you so I could sneak in close enough to slice your head off."
MBF: "You didn't bring your sword, remember and Pewter allows me to withstand anything else you can deal out."
RJF: "In the confusion I had quickly fashioned a rudimentary sword out of a stick and some obsidian, held together with straps of fancloth from my cape."
MBF: "Why didn't you just use some leather rather then....wait, I don't care, it's your cape. Besides, it doesn't matter; I am burning Atium so I saw your attack coming anyway."
RJF: "AHA! You fell victim to one of the classic blunders! The most famous is never get involved in a land war in Cairhien, but only slightly less well-known is this: never go in against a warder when he is only the distraction. Get him Rand! Pew Pew! Buzzzzzzz!"
MBF: "You're an idiot."
RJF: "I spit upon the ground where you no longer ever existed."
Now obviously, one of these fans has allowed his bias to cloud any rational thought. First off, it's steel-push, not iron. Second, we don't even know if Luthadel had any lemons. I would also like to clarify my opening statements: witnessed is probably too strong of a word, perhaps imagined more closely represents my involvement.
