Passive laning Caitlyn:
Run 21 offense, 9 utility for the mana regen
1. Get traps at level 1
2. Push the first three wave with auto attacks when your support is done warding river so that the wave reaches tower
3. Let the lane push back to the middle of the lane while setting up these traps:
Make sure the enemy cant run through these traps without getting caught
If done right, the enemy can only run through the top side.
4. Now comes the fun bit. Whenever they step on a trap, Q them and auto attack them to death.
Whenever they try to enter the lane through the top left side, Q the entrance and poke them down again. The Q width is large enough to hit them 100% if you spaced out the traps well
This will deny them all the farm if they don't use skills.
All you have to do is last hit and freeze the lane in the middle of the lane. If you screw up and push it accidently, just push 2 more waves with auto attacks so it comes back to the middle of the wave.
I can't imagine a low elo player being able to farm at all if you play this right
