For the record, i've been probably ganked about 7 times, 5 in STV. The whole ganking stereotype pve players have on pvp servers is pretty sad.
Oh and the sheer fact that ANY class has a way of running away from another player reduces the likelyhood that you will die.
Druid-Roots, Nature's Grasp, Travel
Shaman-Frostshock, earthbind, travel
Rogue-Vanish, Sprint, Gouge
Warrior-Hamstring, Intercept nearby mob
Paladin-Divineshield+Hearth-out
Hunter-Concussive shot, Wing Clip, AoC
Warlock-Fear
Priest-Fear
Mage-Blink, Nova, Poly
Frankly you deserve to get ganked if you don't know how to play your class.
