Being nice doesn't get you far in this game.
Most of the challenger level people aren't nice people. It's about being good. So saying being nice and having a good attitude doesn't work. You don't climb because your nicer than the other people. Teams don't exist in Bronze games. it's 5 people who are stuck together some of them trying to climb, some of them trolling, some of them being idiots, some them not caring if they win or lose. These are just facts.
