A friend of mine is starting league for the first time
Going to be fun seeing the game alongside the perspective of a fresh pair of eyes
What advice should I give him?
He said he stumbled upon some vids suggesting nocturne as a good champ for newbies.
He described nocturne as a snake like creature. Ah the good times of being a newbie..
First time I got karthus ulted I thought the light was the game celebrating me for doing something awesome and then...dead lol

should be a good roster list for him to choose from and start getting to know the roles, see what he likes (Most of them are also pretty cheap for BE or RP).
