I'm more amazed by the fact that Universe is the one leaving, I still think Cr1t is nowhere near the captain ppd is/was and Fear certainly won't be a better captain from a core position.
As far as the meta goes, it really is midlane above all else, except that now you can throw extra 2 heroes in there if need be. I think Liquid has been a bit of a trendsetter here, eventually every core player will have to be able to play his hero pool from mid/safe/offlane, because that's the direction the game is going, the matchups are that important, there's ever less time to catch up, 20-25 minutes is almost late game.
