Right, the jungle is hard, but the benefit you got from having a jungler is SO large. An AD like Yorick (who has lots of poke and decent sustain) or Olaf (who scales pretty hard with levels on his E and has poke/sustain) can usually handle the 2v1 lanes, albeit with a slight CS disadvantage.
Do you guys disagree that jungling provides a huge advantage?
Games are going 30 minutes on average because it's just so hard to push an inhibitor when the other team just keeps coming back for more. Whats to risk when you can just respawn before they can win the game anyway.
