From the post:
Today is the final update for the Guild Identity Cards (GICs), which also represents the close of the public preview period. We would like to say an enormous thank you to everyone who has engaged with this process and provided feedback to us. This has been a truly thrilling experience to be able to openly discuss and debate different ideas with you all.
Today we will be showing you the GICs in their final form. This is how they will appear at the Guild Identities tournaments that will be running at both SteamCon UK and SteamCon US. Please feel free to come and talk to us about Guild Identities, both the ones you liked and the ones you didn’t. Additionally, please feel free to continue to play Guild Ball events using Guild Identity cards. Even though the preview period has come to a close, the feedback threads will remain open for anyone who wishes to add further match reports.
