Hearthstone ranked play is currently disabled. Technical issues have meant that players are as yet unable to play their matches for the start of the March season.
Here's everything we know about Hearthstone's Year of the Raven.
Going to the Hearthstone client still allows you to click through to begin a ranked game, but clicking play brings up an error message telling players they can’t connect to their game. Blizzard tweeted last night to acknowledge the issue, and when I attempted to load up a game a few minutes before time of writing, I was still seeing the error message.
