have to be a warlock to do this
at ZF get ontop of the big wall and just dot the **** out of lower level classes going into this instance and if they try to or another level 70 tries to retaliate..... the only way they can hit you is by getting on the wall or if another lock comes
if they are infront of the wall ERROR: target is not in line of site
if they are behind you ERROR: target is out of range
