AW agreement - sharing defender rating
Simply put, Kabam took away defender kills to encourage 100% completion of AW maps so you can die and revive as much as you want without hurting your chance of winning. Now we can just keep logs and share defender rating and one side doesn’t even have to pursue 100% completion because why do it when you know from the beginning you won’t win. This is probably not what Kabam had in mind when trying to make more money by alliances spending.
