Ive been playing jungle a lot and I love it. but I'm not much of a heavy ganker I really only gank when I see a really good opportunity starting to rise up like your wave is pushed more than half way and maybe the enemy team is low
People tend to get on my case about ganking saying that I'm at fault and I don't believe this to be true. I believe that if you don't have a good gankable lane, if you aren't getting prio for objectives, if your playing too pushed up instead of playing back and fourth then you simply don't deserve ganks.
I'll scale perfectly fine if I just keep clearing and invading and playing for picks after a bad fight. it's up to the laner to either not lose or get sufficient vision to avoid the enemy jungler if they wanna play pushed up
