Don't lose heart, jungling is a bit difficult always at the start. Once you get the hang of it, it's quite fun. If you'd like I can give you a quick run in a custom game or watch your jungling in action and give tips. My nick is Olmond on both NA and EuNe servers. If you play in either and want some help, just message me through the forums....Its official I am never jungling skarner again...
I can't learn enough in a bot match. I am still thankful for all the help but I don't have the jungle knack.
I'm just gonna stick with laning teemo and riven...
Also bot games are sort of a bad place to learn about jungling because A: bots are never aware of you B: bots die easily even without the influence of a jungler C: people don't rely on you.
I can say my own climb to knowing my way around the jungle wasn't pretty, but now I'm really confident with it.
