please stop, your arguments are really dumb and are borderline trolling at this point.
No, we do not need to consider the people incapable of hearing because the original developers have not considered.
If it bothers me so much, I will not add it. We are not in the business to cater to every disability. Maybe we should hack the game so that blind people can play as well. or make it for people who lost their sense of smell, touch, or taste, including every combination.
At the end of the day, if you are deaf and need closed captions, that sucks. Game console developers should have added a way to make closed caption work. But you are the one that is going to need to place effort into getting a game that works for you. Other patch developers are going to work on patches that work for them.
