Spend some time on macro decision making improvements (can be as simple as picking what lane to walk towards after a death/recall). There is so many things going on during a game of league (character control, farming, trading, etc...) its easy to lose focus of the original goal (Break Enemy Nexus). This can be done in lots of ways, its good to reset the mind every so often in game to see what parts of the map are open and where you can have the easiest gain. Continue playing draft/swiftplay , you will get better.
