Coordinate In Champ Select!
I'm tired of dodging games because people entered the lobby late (mostly me), called a role, and nobody informs them (me) that said role was already called. I get 15 minute wait times pretty frequently because I'll call top, nobody will say or pick anything until 10 seconds left, then someone else locks in top and says "wtf ddl" right before the game starts, so I gotta use my lightning reflexes to alt f4 before the game starts. And even then, often times, the game'll start anyways. SO!
Coordinate! Talk with your team, help people figure out if a role was already called, compromise and work together, it's really frustrating to see games dodged so often because people will call a role and walk away, or lock a champ without calling and walk away, only to come back to - SURPRISE - someone else took their role because they didn't stay and pay attention.
