To those of you who play champions "first time" in ranked.
Just don't. It ruins your teams experience. I just played a game where we had a cho'gath who picked him and then said "what do i max on cho, this is my first time and he looks fun". He fed his lane who snowballed the game. Please, when you plan on playing a champion in ranked, practice it in normals first to save your team some LP. Sometimes it does work, but most times, you end up 0-10 like my cho'gath in my game. Save everyone some LP.
