I want to rage my way up to Rank 3 really fast and i have a few questions.

1. How long will it take?

2. Will I get banned if I rage really hard in public?

3. How often do you guys get kicked for doing that?

Thank you for your answers guys!

2. can't get overwatch ban from casual
3. get others to join from shoutbox and you won't get kicked much
