I'd really like a few of the nearly unusable champs to get a buff. I understand how adding a new champ every two weeks totally upsets the balance of the game, and in its own way keeps everything balanced, but there are some champs that really need a rework, especially with Season 3's new dynamic.
That's the plan starting from now. Less champs released, much less and a ***ton of reworks to happen.
Also, they mentioned it was still preseason and things would change very soon, notably regarding the jungle (since it killed many champs and overpowered others).
