Right now I've only tried Naut and Shen. The clear overall was fine, i wasn't close to death or anything like that. But i'm so use to staring boots and having the old masteries where you easily get +5% move speed. So at early stages of the game I'd have close to 400move speed, now since i have to start with the new item I'm only at 355 or so. Which makes a huge difference when it comes to ganking. I'll just have to get use to it though, and maybe try the 2% MS when out of combat. Also for those of you that have been using tank junglers, do you build the spirt stone early, or hold off on it. Both times i build it early on and then i followed that up with the Spirit Item but i felt like i was very squishy.

PBE experience was just fine, mostly. I've been having fun with jungle Rengar and jungle Kha, with a spot of Zed on the side.

After a couple games I've found that it's generally acceptable to just sit on the machete/spirit stone until you have a couple other items, then upgrade it when you start needing more out-of-jungle effects from it.

e.g. machete, boots, BORK for a lot of the more dps-y junglers.

From what I've gathered they want junglers to focus more on fighting each other than ganking lanes. Not sure why they would do this while preaching "more aggression is a good thing," but that seems to be the case. Not sure how I feel about the jungle as a whole, but if I find I can't gank much then I think they may have made jungling worse than supporting, lol.
