Addons that are intended to track hunter's autoshot are currently broken. Specifically, Sorrens Hunter Timers. I used Sorrens and, later, quartz from vanilla up till I quit before cata and works on every vanilla server I've played on. Other addons like Bearcast track on hit, which are fine for melee, but ranged have a delay due to travel time.
What it's supposed to do: Track the autoshot itself to aid in weaving aimed shots and in kiting for pvp.
