"Just gank Caitlyn if there's traps at your turret preventing you from even farming under turret."

I love people saying that. While conveniently forgetting it's possible Caitlyn and/or her support aren't complete idiots, meaning they'd ward for said potential gank.

1. Jungler comes, Caitlyn and her support back off.
2. Jungler comes, Caitlyn and her support don't back off, but just place traps down in front of her/the enemy jungler and make it dangerous to even path towards her to get involved in said gank.
3. Case 1 happens, jungler eventually leaves to help other lanes, the traps are still there unless the enemy ADC/support decided to completely ignore and not help their own jungler just to pop the traps, except in which case the enemy jungler would probably be dead because of the 1v2. Caitlyn pushes again and traps are still there and/or she just puts them back down in front of your face.
