There was nothing wrong with old jungle.
There really wasn't - I've been playing in the new jungle and I can't say much on the goodness of it. What your reasoning was directly contradicts with the reality of playing it - good thing devourer is gone, because now afk farming on anyone is perfectly viable and ganking lanes is secondary to leveling the fastest to keep up.
Don't get me started on how weird the small fruit mechanics are, and the fact the river plant is broken as fuck either.
