I don't know that the ganking is worse on KJ, but is definatly bad. Who waits by the Dark portal zone in to gank people? Forget mining in sholzar if Horde is there, they will kill you for a node. Dailies are touch and go on certain days also. I guess it comes with being PvP server. Carebear has it's own problems, but I always seem to land on Gankland
