Emerald Dream Realm PVP

Emerald Dream is suppose to be its own realm and shows its always full or near full… WHY THEN IS THERE ALWAYS SO MANY HORDE pvp and not enough alliance pvp. Never get any help and am so sick of the awful balancing. I am ready about ready to quit. Love to pvp but being domesticated and dominated by 20 to 1 is RIDICULOUS!
