Jungling Pre-30
I understand that 1-30 sort of a preparation for end-game content. All the mechanics and play-styles are solidified during this time. However, I have come to realize that although things such as mechanics are important, there are also certain strategies that end-game meta possesses that pre-30 meta do not do a good job in educating their players with. I can list a bunch but I would like to discuss about jungling pre-30.
My argument being that runes/masteries seems to act as a barrier rather than to optimize jungling efficiency. Without the proper runes/masteries, it seems that jungling efficiently becomes exponentially difficult if not impossible. Respectively, jungle balancing is geared towards post-30 meta.
It is my belief that the sooner players are exposed to the core concepts of the game, the more accessible this game will become.
