How to carry from top lane once you've won lane, and your team is feeding?
I'm winning lane most of the time in top lane but it still seems irrelevant when my team feeds. I've tried splitting with champs such as trynd or darius but when I die 3v1 or 2v1 and no one translates that into objectives it seems pointless. Team fights are generally lost if the enemy team is fed, because if they're fed then they're REALLY fed and I can't trust the team.
Doubtless I'm making mistakes as I am unranked so any tips for carrying?
