Title basically says it all. I've been playing quite a bit and I knew this would be a problem sooner or later, but people have no incentives to stay in the game if they get bad items or no items in the early game. In the future, this may lead to a situation where three or four players quit early on, leading to a much less interesting game.
I'm also not sure how Riot wants to address this issue. There are many ways to solve it, such as penalizing quitters or incentivizing players to stay in the game via rewards the further you get.
