It is too easy to be counter jungled in these seasons.
All it takes is for the jungle to not worry about taking any initial camps and just wait out for your jungle to engage either red, or something of that nature, wait for them to become low, and then assassinate them. It works best with people like kha, and maybe Eve. The fact remains though that jungle camps are leaving a lot of champs far too low after clearing in the early game that enemy JG champs can far too easily get a kill from it.
