Ok to give some people who have no clue about Raiding efficiency This Item could be nice for a Marks or Survival hunter.  1.9 speed X .85 = 1.62 Base speed with Quiver for your autoshot.  Steady shot has nothing to do Weapon dammage,Arrows, and  scope dmg unless you use a crit scope.  So from here you say how does one get the shot rotation to maximum Efficiency.  You Get 7% In Haste Items which for Raiders is not difficult to get and that brings Autoshot down to 1.51....So from here you L2 Maketh Das Macro and your steady auto can basically fire at 2 shots per 1.5 seconds.....If you are really good you can mix an arcane shot being that it is an auto shot and per every 6 seconds get an extra shot in.....BTW when I am raid buffed my Base crit is 45% with my 4 piece of t5 having my steady shot at 50% with an occasional +10% crit bonus for Master tactician.....My crits never hit Below 2200 with Sunfury Bow while raid buffed.
      Some people will try and argue that they can get an auto, arcane, multi shot, auto rotation and they certainly can but Multi shot is on a 12 second cool down and both shots cost tremendously more mana....
