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.
