Not sure if anyone posted this here before, but I'm just trying to get out of leecher status. I've been playing a hunter for a while now, and I've noticed that the marksman talent, Rapid Killing, which gives a 20% increase of damage on your next Aimed SHot, Arcane Shot, Auto Shot after killing a unit that gives experience/honor will work for both an Aimed Shot and an Arcane Shot. The trick is to start an Aimed Shot with plenty of time left on the buff, and spam your Arcane Shot macro while it's casting, thus, right after the Aimed Shot goes off, your arcane shot will as well, and both will do 20% increase in damage, if screenshots are needed I'll get back to this post tomorrow.
