It's useless advice, being in or out of position does not stop you from being CC'd, nor does it stop WAR from being able to pull you with Blota. There's only so many places you can be on the map whilst contributing. Melees are either playing on the point or harassing ranged and ranged are usually off the point dishing out damage. If a WAR pulls a range onto the point are you going to tell the ranged "You were out of position."?
The terrible map design only exacerbates this problem, 2 out 3 maps are nothing but long sightlines for ranged to harass melee with barely any corners for melee to play around, on maps like these, what exactly does it mean to be in position?
