Well I suggested to Game Design to reduce the duration to around 1 second and/or guarantee that the message can be hidden by the player manually easily without the need of clicking on it. On top, they should check the positioning and verify that important areas, other windows, close-buttons of other windows are not overlapped by the system-message. And i forwarded the feedback that some of you also want to disable this message in general. I will keep you posted on this topic.
I am looking forward! I am curious about final version of system messages and much more about new non-gold event. I hope there will be more info in several days!
