If you're referencing the whole "follow your laner" idea, sometimes you should, but not in the idea of just walking into the jungle alone and getting jumped by them. If you're laning against some champion that tends to roam, pinging is always good, like you mentioned, but running tp can be pretty helpful if you are able to respond to them ganking. Another thing that you can do is to shove the lane and damage the tower as much as you can.
I'm not saying you should always follow your laner but there's way to help other than just pinging and hoping for the best, because I'm aware the majority of people either dont use the map or dont listen to those pings.
