They just dont get enough. Even if they go from camp to camp to camp and not do much ganking, they will still fall behind the laners, something pro junglers in SR wont. I think that the camps should AT LEAST, provide more Xp, and some more gold. Cuz right now its very underwhelming to be a jungler

Junglers in SR are always behind in gold.

They didnt used to be, before they ruined the jungle. ~_~

I really like jungling in the Twisted Treeline. You do get a little behind, but that's gonna happen on summoner's rift as well. I feel like I have a real responsibility for keeping an eye on my team's altar when playing as the jungler and I enjoy that. You have a real presence with both lanes, so you should have a hand in most of the kills, which helps a little in gold.

Also, Rengar has way too much fun in that jungle X)

I have never had a game where there were 6 people just farming like they should to see how this happens.
