The pacing of games currently is way too fast

Junglers are still leveling at an exponential rate, which is a big part of the problem. As a result, snowbally junglers or farm heavy junglers can gank or power farm for 20 minutes and basically end the game by 15-20 minutes by ganking or emerging from the jungle 20 minutes with levels/gold advantages across the board, win one teamfights, take Baron and push to win.

As a result, this has made the game very early game focused and it makes who you play and what you build extremely linear. This isn't good balance nor is it fun. It makes the game less interesting when 20 minutes in, you're already knocking on somebodies inhib towers.

There are other problems too, some items need to be removed or nerfed but they don't contribute to this nearly as much as the power junglers have currently and how utterly laughable it is to take towers.
