Blizz merged vashj with these servers and not even mentioned in the title.
Also as Vashj is merged with mostly Alliance servers. Now it’s a real pain to do missions as it’s overrun bye alliance and so almost all mobs are tagged by alliance players.
So thank you Blizzard, At least you should have given ppl the chance to change servers for free or make it possible to tag the same mobs as the alliance.
PVP is already impossible, now even normal questing is a pain.
