Really tired of losing games because of someone else's connection problems.
Sometimes you're a liability to the team and have some areas for improvement.
Sometimes you're tested on your ability to carry someone else who's being a load.
But it's just irritating to do everything correctly, have everyone on the team coordinated and performing well, only to suddenly have the game turn into a 4v5 at a critical moment. There needs to be better detection/forgiveness of these situations. I'm sick of being punished for something that has nothing to do with the game or anything I did in it.
