Pre 10 Jungle
Dear Riot; I was playing on my smurf account practicing the new preseason and let me tell you... The jungle is WAY WAY WAY too hard for players under 10.
With the inability to pick up smite OR a jungle item there is no possible way a pre 10 can play the role of jungle. My main is gold v so I know how to play jungle and even with my movement in jungle to avoid AA from mobs, armor, masteries, I either have to back right after a camp or die at the 2nd or 3rd after.
Every single game that I have played with a Jungler in preseason has either fed, rage quit, or was successful through smite. I unfortunately fed (the jungle mob) so hard that my top laner raged and intentional fed because i was too far behind to help him gank his losing lane.
