I've been talking about the Spell Reflect and Combustion macro's with a friend of mine.
Apparently this also works for Misdirect as well.
This isn't nearly as ground-breaking for PvP as Spell Reflect and Combustion, but it's IMMENSILY crazy for PvE.
Test it out and laugh, this is crazy.
Edit: DUR I NEED TO TYPE WHAT TO DO.
1.) Buff someone with Misdirect
2.) Fire a shot
3.) Sit before the shot lands.
4.) IT doesn't eat a charge of Misdirect.
5.) Profit.
