Preseason is not a failure yet.

What makes a preseason fail? It's when what makes the game broke. During preseason go into the live season.

So many threads right now are complaining about what is broken or how broken the game is. Keep it up, it provides visibilty of the problems. I'm not trying to condemn those kinds of posts.

I would just like to remind people that most of the balance on champions right now are what was on the old rune/mastery system. Riot tried to preemptively buff some base stats but that was never meant to balance things considering how little data they can get testing (even pbe) compared to putting it live. There's a new system to balance around and the new rune system has the potential to be easier to balance around as it's less pregame stat buffs to balance around.
