I would really love the option to hear the comments of other characters in the respective language of their player.
With 3 or 4 (or even more?) different language versions and the megaserver system in place it would be kinda cool and interesting to hear more voices and in different languages. This could add a lot to the atmosphere within the game.
The world would feel more like a place where people from different corners of the planet come together!
This should be an option of course since some players may want to understand the character’s comments for tactical purposes without having to learn them in different languages. (Which actually isn’t that big of a deal though! )
