Need late-game tips - Strategy on how to win late game.
I need some help understanding where I go wrong with my game play. For the last, I'd say, 8/10 ranked games, I've won my lane, roamed to helped other lanes, tried to drive team strategy, focused on objectives, and tried to do everything I can to help the team push for a win. The issues is I haven't been winning, and don't understand why. It feels like team mates are never cohesive, other lanes always fall behind, and honestly like I'm playing with folks who are fresh level thirties against seasoned vets. Elo hell comes to mind because I've heavily tuned my gameplay over the last few months and always do well early/mid. Than, the team has to come together and things fall apart.
Obviously every loss or bad play isn't entirely my teams fault; I'm not the perfect LoL player. So I'd like some pointers on how to better control late game since that's where things tend to fall apart.
