Sooooo, jungle is better in the fact that power ganking is much weaker than before, but they really didn't buff power farming as much as I thought they did initially.
That means that jungle over all is weaker/worse. Not to say that I am entirely unhappy, but maybe something needs to be done to keep levels from getting out of hand for 2-3 ganks.
If I try to make 2-3 plays not related to farming or getting farm, mid will easily be 3 levels ahead, which is really bad. Bot lane will usually pass a jungler that either got invaded or died ganking. Currently the late early game and early mid game EXP is a bit too low and needs to scale a bit harder in that area.
Beyond that I'm very happy with the jungle changes, but I would not say I am happy yet. Over all this is a better jungle IMO once balanced, but that's all that is my opinion. What is the source of your stats?
