When do chests reset?

When the new season starts.

1.) Who's the assclown that downvoted this? Is a legitimate and relevant question. Upvoted that for ya.

2.) I don't even see why chests would be reset... There's 200 some-odd champions. You'd need like 600+ keys to unlock them all. How would you ever get that many keys?

If you want more chests, go play some new champs in norms and get their chests. Its tons of fun, and can take you outside your comfort zone - which is where you learn the most.

I just learned the other day how Urgot's W actually works, and how to counter it. Playing new champs you wouldn't normally play is a great way to develop and improve your overall game strategy.

But hey... if they're gonna reset... cool I guess. Means nothing to me. I just don't see why its necessary.
