For Battlegrounds, I assume?
This is the spec that I use for farming BGs (although I have swords, not that it matters). After PvPing as both Shadowstep and a standard 19/42 Combat build, I can say without a doubt that Shadowstep is the way to go.
Hemo maces (something like
this) is a PvE build, and one that's more suited for 25-man raids than 5-man and 10-man instances. Don't bother with it in PvP.
