i'll paraphrase for you and everyone else so everyone can follow the conversation
OP - "when playing karthus and using his ulti you can choose who gets attacked with ludens echo by swapping names around"
Me - "no duh, plus you can do this. it's actually pretty easy - links video"
You - "PEOPLE SHOULD TAKE SMITE LESS OFTEN THEN! (sarcastic jerk voice with herpity derps included) "
Me - (trying to be nice) "Smite actually helps a lot as a jungler so i wouldnt recommend it"
You "I was kidding because i thought you were kidding"
Me "i'm not"
You "Yes you were. here's proof that i know more about what you said than you do even though you said it and i could have very easily read it wrong, but since im an ass even if that were the case im still going to argue with you and make it look like you're the idiot because im an ass."
i hope that helps with any confusion.
