Champion help
So i am a relatively new player that is really not that good at league and I want some help finding a champion. I need someone I can learn the game with better. The champions I have are Vayne, Draven, Yi, Sivir, and Tristana. I am looking for a champion that is a little bit forgiving where I can make a mistake and not get destroyed. I almost have 6300 IP so anybody is an option. I have had more experience with ranged champions but trying something new is always fun. I play very offensive and have played every lane.
MY STRENGTHS: Skillshots, ganks, ARAM
MY WEAKNESS: Laning, being to offensive
If anybody has any champion suggestions I would love to hear them! TY
