Early Game
Too many games are over in the first 10 minutes and you end up just waiting until you're allowed to surrender. Most games now are one side getting completely stopped. There are hardly any long, fun, tooth-and-nail type games where you struggle for every inch. I think the reason for this is because too many champions have severely overpowered early game, while other champions have to farm up five or six items before they become relevant. There is a huge disproportion of power among champions early on, which allows some of them to get huge early leads, which are usually unrecoverable later. They need to balance out the early game.
