ward chock points in enemy jungles
hot spots like main entrances not just bushes your wards should cover as much ground as possible so that their champion will most likely walk thru the area to get to another lane and you will spot them by warding u can see where their team is setting up or farming at and you can rotate around and take towers for free or objs such as their jungle camps towers dragon scuttle crab etc.
If you see their jungle bot late game and they have no way to get to baron quick. you should try to do baron with your team since the jungler is not around . the same goes for if their adc shows bot lane late. its a easy time to go to baron because they have no adc to win or contest the obj..
1-3-1 split push always works well esp with baron buff
make the enemy team follow you around not the other way around... do this by warding well and contesting more then 1 lane at once
Manage your minon waves ... your minions coming out of ur base is coordinated with your enemy minions >ex. When ur minions spwan their minions spwan when ur minion passes ur tier 1 turret their minions are passing by their tier 1 turret... keep this in mind when you are away from your lanes so you can see when and where the waves will crash so you can farm better
This game is all about thinking ahead thats all there is to it
