Going to x-post this because I know it's going to come up a lot, about our priorities and basically, Garen, why?

We have to space out our champions from High-Risk to Low-Risk. If you've seen what we did at PAX, we've revealed Sivir, but we were honest in saying she wasn't next. All the champions you've mentioned are high-risk, with maybe the exception of Nasus.
Garen is Low-Risk and high reward. Not our worst executed champion, but of tremendous player value in how common/approachable/archetypal he is.
He was relatively "low cost" for how much value he'll bring to players.
Sion, Eve, etc, are all on the List. Sivir is coming up soon, but she also, was high-risk, requiring a lot of ideation.
I can non-hyperboilicly say that he's really epic in his execution and it's a well deserved VU.
