Getting kiting right is key to improving your League of Legends game as it allows you to gain distance from the enemy while still damaging them and potentially sidestepping their attacks. If they weave in and out of range while still letting of a barrage of auto-attacks, then you know they've mastered orb-walking. One of the many ways you can tell if an ADC knows their stuff is by the way they aggress on you in a teamfight, or how they handle themselves on the backfoot. Orb walking applies predominantly to those playing the ADC role as it's so essential to their damage output, but it also applies in a broader sense for other roles aiming to land their auto-attacks and stay on the move. If you’re starting to get serious about climbing the ladder in League of Legends, then you’ll definitely need kiting/orb walking/attack-moving (whatever you want to call it) in your repertoire of core mechanical skills.
