How do you jungle?
I know the basics of jungling but the biggest issue I've had with jungling is clearing the camps. I watch all of these high elo junglers on streams and videos and even on the worst of champions they manage to do almost perfect clears with 2 HP pots or less and still be at full HP and ready to gank, but when I do it I run out of HP by the third-fourth camp and can't even gank.
Is it kiting? Is it poor runes? is it poor masteries?
would take the first route, and
could take the second route.
Killing Scuttler takes so long that it's better to back. The extra camp is worth more gold and xp, but if you're forced to back without it, you can upgrade your flask anyways - because if you couldn't finish the camp, you most definitely had flask instead of 3 pots.
