Just a small exploit.
Currently the Glyph of Direction is bugged and will cause your Misdirection to have no cooldown. I have found this very useful when running 5mans for valor since 1 multi-shot at 511 ilvl generally takes threat off bad tanks.
Please note that this is NOT the Glyph of Misdirection. The Glyph of Misdirection only resets the cooldown when you cast it on your Pet. The Glyph of Direction causes it to reset when cast on anyone.
