i never heard any french or german in about three years of playing!
Actually back in the day Seraph had a strong following of french players(currently known as bismarck) not so much anymore though still know a few. I've only met about 4 german players in like 8 yrs playing(2 in my social) but like you said probably a server thing.

Btw; i once had a pt with everyone but me speaking arabic in thickets O.o(THE TERRORIST ARE ATTACKING VANADI...i kid i kid)
