I'm going to put in a weird opinion here, and it's going to either provoke a lot of thought, or get a lot of hate. Not sure which, maybe both.
The jungle right now is in a good place, i feel. I like the harder jungle. I like being forced to make decisions about what I'm doing and how i do it. I feel like the jungle is mostly good where it is - with two exceptions.
As is widely posted here on the boards, the handful of champs who don't have to make decisions quite as carefully as the rest - the top tier of jungles need some nerfs. J4 got smacked a little, we'll see how he fares and go from there. Vi and Lee could use a smack too. Because they are strong - and their decisions seem much easier than say, Nunu, trundle, diana, etc.
EDIT - then there are the lower tier jungles, like Eve or Wukong who aren't allowed any leeway on decisions - Thanks to ForPortal below for bringing that up. IMHO, those champs need some specific love, not sweeping jungle changes. ENDEDIT.
The experience gap is a touch large. I don't mind being one level behind my sololanes. I do mind being 2 or 3 levels behind. This is tricky to balance though, so if Riot doesn't get to it immediately, that's fine.
The difficulty of the camps though, the smite changes and mini-buffs? I genuinely like those a lot. It increases the strategy involved in playing.
