Hunter misdirection bug

What you'll need is the minor glyph, Glyph of Direction, and a target to cast Misdirection on.

After casting Misdirection on your target of choice, cancel the buff, then cast it again. For the remainder of that buff, all threat you generate will be transferred to your Misdirection target.

If you need to renew this buff, just cancel the buff and recast it. The exploit in this is that it gives you unlimited Misdirection with no cooldown.

/ Macro

Spamm this on the player that getting attacked.

/cast Misdirection
/cancelaura Misdirection
/cast Misdirection

Works!
