Ranked Battles 2019 was originally planned to be launched this month. However, after numerous tests, we have determined the current structure and mechanics of the system, combined with the density of planned in-game events, will not be optimal in terms of player experience for the NA server.
Therefore, in the best interests of our valued players, we have decided to cancel the launch of Ranked Battles in NA in order to focus on the modes of gameplay that will best suit your needs and expectations. Please rest assured you won't miss out on any of the potential rewards for Ranked Battles, as these will be suitably reallocated to other activities.
We appreciate your patience and understanding, and look forward to bringing you many more engaging events this year.
Stay tuned for updates, and see you on the battlefield!
