This happens to me a lot as a split pushing Nasus who is doing well. Like, do you not see my q's on the turret and the damage I do? I would rather if they ping me MIA or danger in the upper jungle path so i hide and recall in case i cannot take turret on time.
It's always the nasus's fault when a team loses a 4v4 across the map
lulz XD It's always the one also taking blame and covering others.
When people do this it makes me want to die. Over pinging is the woooooorst especial if the person doing the over pinging is a feeder....
