^ What he said.
Although I will say I don't bind HS to mousewheel because I like to be able to regulate it depending on my rage levels/current threat. If I'm low on rage I'll stop hitting HS to make sure I have rage for shield slam, which is far more threat. So typically in my parses I do have melee hits, but HS is still my number 1 damage dealer, usually around 34%.
Also I have a really bad habit of constantly zooming in and out with my camera, so binding HS to the scroll wheel didn't work out too well.
