False, it's not necessarily used against melee opponents and it is fair after all because it is a skill. I'm a pally and ill kite archers in order for them to miss a blast or shot. It's all timing and knowing your distance, and you never want to run in the process of kiting just maintaing a good distance from the opponent. In the event of running however players will get mad at you and you should not be surprised at all if this happens.
