Silver kids are so adverse to help
You can ping them to back off since you know j4 can actually kill the 0/3 Tahm Kench who is staying in lane with 300 HP.
You see said j4 coming bot lane with nidalee to dive your 200 HP bot lane and ping for them to back off well in advance.
What happens?
"Stfu stop pinging and come help."
Now how are you supposed to fix it?
