The thing people seem to forget is that if the enemy jungler is in your lane, they AREN'T in ANYONE ELSE'S lane. If you are being camped as hard as you say you are:
- The enemy top lane is splitting XP with the enemy jungle, they are both behind in levels.
- The enemy jungle is not farming, he will be behind in items.
- Your other lanes don't have to worry about jungle pressure, so they can be as aggressive as they want, and your jungler can gank them for free.
You get all these benefits, and MORE, and the only thing you have to do is play safe, and stay alive. The enemy was literally handing you the game on a silver platter.
