Well...you know...it could be that JP, GR & FR players don't want to play with "Ugly Americans"? Perhaps it is they who are asking for Labeled/Segregated servers?

Personally, I prefer playing with non-English speaking peeps because Americans shout/say some pretty stupid sh*t in game and it gets annoying and breaks my "Immersion" in the game. ;>P (#1 reason why I disliked WoW & SWToR is just as bad)

Sure, JP, GR & FR probably say some pretty stupid sh*t too but since I can't tell what they're saying, it doesn't bother me. ;>)
