All game design is not feelings because feeling change based on the consumer. There is also design elements that can be objectively bad and objectively good. That is independent of the subjective nature that the consumers have of the design. The rest of your post is just nonesense to pad your ego of being this super smart game designer that knows so much more then Blizzard.
Maybe just move on from the game? Your criticisms aren't even about what their goals are because you know you bashed the Ember court just for being the ember court. That is the problem when you act all arrogant and move the goal posts for each post. You are analyzing your feelings of the content and calling it bad because your feelings do not match their goal. That is 100% different from bad game design principles.
