Frenzy
This skill is just insane for single target dps. I always had problem with choosing between bash and frenzy, but after some testing, in the end I fell in love with frenzy. As for rune, I saw a lot of people use Sidearm - while it is good for add packs, I find maniac to be better for boss fights without adds or situations in which you need to focus one target and nuke it down fast (there are a lot of such situations when you face champion packs, killing one champion out of the pack might be the only way to go with some combos you will get in inferno). And if you will be stacking life per hit stat (and I recommend doing that actually, more about that later), 75% bonus attack speed is just insane.
