Compete in organized gameplay with similar teams

I've been playing Overwatch since it was fully released. I've been Diamond in Season 3, 8, & 9 and pushing diamond in several other seasons. I'm a coach-able player and a quick learner. I'm interested in joining a team of serious players looking to improve and play as an organized team. I've historically played mostly DPS but I can be known to play tank and support as well.
