Are junglers getting destroyed to easily? (@High camp cooldown)

I have jungled A LOT since the new jungle came out - and there's something which is really bothering me.

I often experience that I finished all of my camps and have "nothing to do", lanes are pushed, objectives are done and counterjungling is too much of a risk at that point - especially when an enemy laner is fed.

With a laner being fed a new problem arises: Somebody like Riven or Zed can easily clear jungle camps and neithr the jungler, nor the midlaner can stop them due to insane damage and mobility.

And due to long camp cooldowns and how experience distribution is handled loosing out on a single camp already knocks a jungler extremely behind, taking 2 camps is close to a death sentence.

As a result, once a laner like this is ahead, he completely takes out the jungler as well. Due to the low power junglers now have early on they aren't even able to apply much kill pressure to that lane either since they'll fall even more behind when camping the lane and can't really gank after a few camps either since they will be too low (unless their name spells "Warwick" or "Xin").

I really think experience distribution and spawn timers have to be looked at. Currently it's a pain to jungle since once a solo lane is lost that's close to death senetence for you as well.

(Sidenote: I'm mainly talking about my experience fighting Platin ranked enemies. It might be that lower ranks suffer less from this issue due to roaming after winning a lane is less popular there)

This is gets leveraged if a tower falls quickly: As a response your teammates will usually start taking your jungle camps, completely knockign you out of the game as well.
