We’ve got one small Duels change going out in a hotfix this afternoon, moving Unlocked Potential from Treasure Pool #1 to Treasure Pool #2. This hotfix will take place on the server side, so you will not need to download anything if you’ve already updated to the 20.2.2 patch.
Dev Comment: We do not expect this change to completely eliminate the possibility of meta-defining synergies that may pop up in duels for the time being. However, we are unsatisfied with how deterministic the passive treasures system has become after the recent change to offer more synergistic treasures. We’ll continue to listen to your feedback, and have plans to further tune the passive treasures system to be less deterministic in the next major patch.
