I think the new jungle is too hard for certain champions..

I may only be level 27, but I used to be good in the Season 4 Jungle. Keyphrase: "used to". There are plenty of junglers right now that do well, specifically ones that have a good amount of built-in sustain (Warwick ban, anyone?). The downside of this is that jungle champions with little or no sustain, like Nocturne and Rengar , are struggling too much in this new jungle. Yes, Nocturne's passive has some sustain and Rengar's W can heal him with a full Resource bar. However, I feel that this is not enough. I usually can only clear three camps at most as Nocturne before I NEED to back, and I can really only do two camps as Rengar. In my opinion, the monsters hit way too hard at level 1, and even the Health/Mana regen properties of the Hunter's Machete isn't enough to mitigate this problem. I think that the monsters should be toned down in difficulty, even if it's just a little bit.

A good example, I recently played a game as Nocturne and the enemy Jungler was Master Yi. When he emerged from the jungle for the first time to gank, Master Yi was already Level 6, and I was still level 4 or 5. Sure I had the Ranger's Trailblazer to help sustain me once I went back, but it didn't help me keep up with Master Yi in terms of farming. I feel this is an issue that needs to be looked into, if it's not already.
