Well I know I've personally put work into the Draft Mode interface, into what stats to track, into how we will manage teams and Ranked Games queuing/ranking. Sure, most of this has been feedback and "this is how I think it should be done" as I have no actual implementation skills, but then engineers go off and make it happen and I have no further updates to give.
Timeframe on RG/Draft hasn't changed since we first said it would be first half of the year. I believe we're still on track for that, so... up to 3 months as of the last official word. That's really not so far away. There may be further updates on the matter, and maybe I have outdated information, but I know for certain that every one of those features is in fact being worked on. We are in fact hiring more dudes. There's a lot changing really quickly here at Riot. I talked to Pendragon just 5 seconds ago. We are on track for first half of the year. If all goes well it will be there before it becomes July. Stay tuned, cuties.
