I know that not using it on shadowflare makes you miss out on a certain amount of dps, and if your goal is to be an extremly efficient dps more power to ya (lol literaly ). If I was in a group where i knew that if i rezzed someone that it would actually throw a whm off cause he is that good, i would turn to using swiftcast and shadowflare in a heartbeat.

Its a combo that is to precious to give up. And is what separates our class from the other dps.
