RLCS or other pro teams

Hello, I am a fairly skilled Xbox One player who is wanting to take Rocket Leauge a bit more serious. Im a friendly guy who wants to win! I have been in the low champion to high diamond range for about two seasons playing with my friends who are low diamond. This skill gap has limited my skills and I feel a good team would push my skills to the high champ it needs. I am a good person for callouts and eventually want to be in RLCS. Overall I'm a good player that believes anything is possible.
