Such fancy stuff as rotations, dives, tracking, and matchups requires too much consistency for a Silver player. However, game fundamentals are important at every elo.
For example, consider back timings. They’re called back timings because they’re the timing of your backs. The timings themselves are literal times, which come whenever you can back without losing more than a couple minions. Each good back timing comes whenever a large wave crashes into an enemy sidelane turret or a siege wave crashes into an enemy midlane turret. Then, the enemy must spend so much time clearing the minion wave that you can recall, buy items, and walk back to lane just as the wave reaches the edge of your turret. In the midlane, the siege minion will eat turret shots, keeping the turret from stealing last hits on the other minions.
Since this is just how the game works, back timings are important at every elo. If a laner can force an opponent to back at a bad time, then he will miss farm. Or, if a jungler helps a laner push the wave to the enemy turret after ganking, then the jungler can secure a good back timing for the laner, letting them recall to buy items without missing minions. It’s almost always a good idea to do this; your ganks will just be flat-out better if you do it as a rule.
A slightly fancy thing that’s like back timings is called lane priority. Whichever laner can leave a lane first to roam or help his jungler has lane priority. If one laner has just crashed a giant minion wave into the enemy turret, then even if the first laner roams or helps the jungler, the other laner must stay at the turret to last-hit the minions or lose gold and experience. If your mid-laner, for example, has lane priority, then you can deep-ward the enemy jungle and take drake or herald for free because your laner will come help if the enemy jungler contests the objective before the other laner can.
How’s that sound?
