Wiz said something along the lines of - Utopia was about increasing design options for civs, Apocalypse is about revamping War, and the next focus is going to be on Diplomacy and Trade. I think everyone realizes that is now the weakest part of the game. War just had to be first because it was fundamentally tedious and actively not fun, and as you’ve pointed out, it was the main interaction you had in the game.
