When they say that they are referring specifically to controller users(using kb/m you would just keep your character facing the monster and not have to worry about it). Whenever I've been asked for help improving dps by a melee, the very first thing I check is how many fewer autoattacks they are landing compared to someone else doing the same fight. Almost invariably the melee using controllers who aren't using lock on have far fewer autoattacks, and seeing as autoattacks are the majority of your damage its the easiest thing to fix.
