Move down in AW tier after win
Reporting this as a bug since I saw a few other posts referencing the same which I would think is rare.
Our ally was in tier 12, won our match (first after the AW changes), and now we're in tier 13... I know the tiers are based on % ranking of alliances, so there's a possibility that with the wider spread folks are reporting in matches that a bunch of alliances may have gained more points from a win and leapfrogged us which would be legitimate, but perhaps something for your team to look into to see if that's indeed what's happening.
