I think a good example of a champion with an early game more than a late game is Draven. His abuse early game (if used right) lets him win early so easily because of that intense DPS.
The thing I'm not excited about for S3 is the jungle changes. I don't jungle, like I said but I think they might be changing how leashing works, jungle timers, stats, etc. But it is a good opportunity for me to start jungling with the new changes.
