One of the most disappointing rules is having an abandonment penalty in place. You get joined in a game with players who should not be in a ranked match to begin with, and get penalized for leaving right after you get knocked down. It's not a comprehensive penalty, and leaves a lot more frustration for the community of people who actually like to compete. Think of a better, more constructive way to penalize players, instead of punishing those who are already frustrated with the match.
