I sometimes feel really bad for my teammates

Because it legitimately looks like they're having an awful game. They're having no fun. I was playing twisted fate mid, and our tryndamere was 5 levels below their riven in the last 10 minutes of the game. He tried, ended with the least deaths in the game, but he just fell super far behind and when we tried to help, their team would help with more allies, not to mention every lane was falling and we couldnt afford leaving it to help.
