Eh... as sad as it is for the rest (and most) of the world english is the universal language of every aspect of our social life. It's kind of a must nowdays, but I do agree that not everyone might be capable to learn the language on a level that allows to freely access media.
Could they do a full dub into another language? Probably, not likely as it takes a lot of time, even more money and finding the right talent. I'm also for general fairness in accesability, so if you dub your game you should dub it for all the languages supported. That cost even more though

On a side note - I always hated dubs made in my language, they always hire known faces from the movies or whatnot and more often than not they do a shit job and I can't help but see the actor not the character. Always prefer the original spoken language even if I don't understand it, becuase you can't mistake emotion behind words. Those are the voices the creators had in mind, and dub actors *always* shove their "artistic vision" instead of sticking to the role they are given.
