The flaw with this argument is that Ablegamers rates mainstream titles for accessibility by disabled gamers, and by accessibility they mean the ability for a disabled gamer to enjoy the main portions of the game's content. This includes the ability for colorblind players to determine mechanics or hazards and clearly read text and for deaf players to do the same, so they can enjoy what the game has to offer despite disability. I doubt Ablegamers has thoroughly gone through the endgame content.
