you miss understood, thaurissan IS a pvp server,
but in thaurissan, the horde greatly outnumber the alliance,
last i see in warcraftrealms ratio is Horde 6 : alliance 1
you can go anywhere and hardly see any lowbie alliance questing.
and since with the new lfd system, there even fewer number.

BUT

there still some player(namely level 80) honor the old school stv, gankbrad, old world pvp.
