Rotational Queue Future Hype!

Riot mentioned that they were going to impliment Rotational Queue, where every 2 weeks will be a different featured game mode (like All for One, Hexakill, and so on), and I am curious which game mode would be your favourite to play when Rotational Queue comes out?

Btw, there will be 2 URF Rotations this year, but not on April 1st (unless Riot pulling some April Fool's joke on us... )
