We would like to kindly inform you that from today you need to have Legion 7.3.5 (26972) to log in correctly to WarCry: Azeroth. This is the final version of Legion before the release of BFA, which we intend to permanently use, including, among others, 4K support, change of the multi-core support mechanism and a number of graphic improvements.
Description of how to download this version of the game can be found here.
