Since the release of the 2.4 patch we’ve been working to tighten up the changes made to help address longer wait times when attempting to get into an arena match. While we’re fairly certain it’s been successful, we’d like your feedback relating to the wait times, how they were before the patch and how they’ve been lately.

As our changes have been continual since patch 2.4, please only leave feedback if you’ve played in the last week.
