Players with horrible connection

Why do they even bother playing? I'm not talking about general lag. I mean the people who disconnect over and over again and after 40 minutes are only level 5 because they've been reconnecting most of the game and logged out over 15 times. I just dont see the enjoyment in in for you. It is so easy to just get a job and buy better internet. And if its not offered in your area.... why not just get a different hobby? Its not fair to everybody else to make your team go 4v5 the entire game. I figure these people must have extreme depression. I understand wanting to withdraw from life but do it on a game that does not punish other people....
