There are two major issues that you are facing which we want to ensure we deal with over the next 6 months. The first, and unsurprisingly, is bots. We want to be able to remove the bot menace from disturbing your experience so you can enjoy the game the way you want to. Later this week we have a meeting with the anti-bot team and from this meeting we will draw up a plan to achieve our aims. We may not be able to share everything we plan with you, but what we can share we will.
