People who hate loot boxes but still want to play Shadow of War can bypass them by simply declining the online ToS.
A simple solution has been found by eagle-eyed players and it’s as easy as unchecking a box in the game. After opting out you will get an “Offline Gameplay Warning”
You will not be able to access any of the online features for Shadow of War until you agree to the data uses described on the prior screen. This includes access to the Market and online gameplay modes. Are you sure you want to continue?
A simple “yes” will make your game free of microtransactions since you won’t be able to access the market. The offline multiplayer raiding aspect will be unavailable as well.
