Because of intence horde dominance on outland realm as they gang low levels behing hire or just in general you try to do quest killing mobs in between 20 other hordes in Outland and 70s killing 60s alliance :) thats some sad experience for others which just makes them start leveling Horde...
And free Transfare probobly wont work either cuz the rate is still the same... In the end there might be only hordes playing on realm.. lol
