So from there it's just a matter of comparing the hate over time between enmity gear and haste gear based on immediate casting, and then again based on, say, immediate + 5 seconds, and if the two agree, then the question is answered. If they disagree, then you could also make the argument that it's too small a difference to 'matter', or to defer to some of the other questions people are treating in this thread.
