Want to help ganking/tank junglers and aoe junglers and indirectly nerf Warwick?

Increase little chicken damage, decrease big chicken damage, and boost their gold and exp reward. Make single target junglers take a lot of hurt from trying to take the camp, but give incentive for gankers (who tend to be more aoe focused and weaker at single target) to take (and smite) the camp since they would, at least in principle, clear it more quickly and with less damage taken.

If you're worried about mids taking them (which you shouldn't be, because mids doing anything other than farming and pushing mid is a good thing), then deal with it.
