How do you deal with your team feeding in the first 5 minutes?
This seems to be the #1 cause of losing games. Before I get rolling and can start to influence the game by ganking other lanes, my team is already feeding the other lanes and making it less likely I'll be able to do so.
I don't know what to do about it other than just accept it as a roll of the dice and assume that, even if I play my best, I can't expect to win more than 55%-60% of my games. It is discouraging to lose when you feel like there was literally nothing you could have done better or different.
Is this less of a problem at higher elo because you have more people who understand how to play defensively and at least don't feed so regularly early game?
