I completely agree, I really hope that multi nationalities make it into the game. Look at Overwatch for example, they have a lot of heroes from different countries and it gives the hero some 'basic' background and it gives some shifting experience for a player.
Imagine a foreign soldier throwing a grenade or giving some information for his or hers team. It gives the game so much more, in my opinion.
And yes, English(American) and German are some of the biggest languages in their player-base. But I think that they should be able to lift up some other countries, other than the 'biggest' ones.
