Go with a skill rotation that fits your playstyle, its literally that simple.
Addons may help you MANAGE your skill rotation, but ultimately the rotation is a function of what you input, not what the game thinks will work.
Play around with your class and find out what works best for you. As a S/Wd i usually went Snipe, combo shot, Shot, Autoshot, Wind Arrow and after that it didn't matter (Since i only played him to level like 37 in Ch 2)
