I'll second the wind sheer macro being built into casting -- that thing is great, I get a ton of interupts out of it -- nothing better then nuking a target and getting the screen shake (that's an add on, it "shakes" my screen when I successfully interupt) and the healer stands there.

Like Asonimie mentioned in his windsheer thread, I've seen people stop their rush and back peddle a few times when I go to flame shock the charger and 4/5 of the other team gets a green burst on their toon =P Its like they're saying "whoa! wtf was that?"
