We are continuing to do everything we can to address the server issues. In the meantime, so that we can give you as good an experience as possible, we are in the process of deploying a hotfix to all servers. This includes various improvements and also disables a few non-critical gameplay features (leaderboards, achievements and region filters). Disabling these features will in no way affect your core gameplay experience.
We will continue to let you know as we have more information. We know it has been said before, but we do appreciate your patience as we complete this latest update. Getting you playing is our absolute highest priority.
