Just a quick update (and some of you may have noticed already), but Solo/Duo queue is now available for play in preseason. If you can't see it, a relog should hopefully clear that up!
Some regions (Garena and OCE) have had this queue for a few days —this is because we wanted to be sure everything was working smoothly before hitting the big red global launch button. The majority of issues experienced with MMR/initial placements should now be resolved, so this should be a smoother ride for those of you who were waiting for it!
Thanks for your patience in awaiting the launch of this queue, I know it's been much anticipated - we wanted to make sure we'd ironed out the issues before launching another ranked queue in preseason. Good luck in your climb, and don't forget to check out the [How to rank up in the 2017 season](http://euw.leagueoflegends.com/en/news/game-updates/competitive/how-rank-2017-season) guide for information on preseason, placements, and what to expect with the launch of the new season when it comes around.
