How to stop someone camping your lane
We've all been there. Heck, I've even done this before. A jungler decides to focus down your lane and whenever it seems like your getting a little bit of an edge RKO OUTTA NOWHERE, or in the words of the mighty jingles, surprise buttsex happens. And yes, even I have been guilty of thinking why isn't the jungler doing anything about this. But after thinking things through I realized riot gave us an ingenious tool to prevent this. Its called a ward.
If you are just relying on your Jungler to supply vision think about this, including a vision ward and two blue wards a jungler can only have about 6 wards on the field at a time if he bothers buying a sightstone. And, your jungler won't want to waste time searching a jungle looking for that one dude who is tormenting your lane. However if you put wards down you can tell whether he is ganking or not, and it'll make searching for that jungler a lot easier for your jungler. Even if your jungler decides, no, I'm not going to attempt to kill that fed Udyr, Warwick, Yi, Nocturne, Jax, etc, you at least have an idea of where he is on the map.
So, instead of complaining to the jungler about not stopping a dude from camping your lane, be proactive and try to spot the jungler before he ganks, by using wards.
