My main is DB/WP and I only have four attacks. Blinding Feint, Ablating Strike, Vengeful Slice, and Sweeping Strike. With these four attacks on repeat, you have a double boost from Blinding Feint and never ending DoT from the Vitals Combo, which is a cone, so with a little moving around for positioning, you can melt entire mobs while focusing on the bosses. It's an outstanding single target killer, especially once you have purple damage procs slotted. It's not a great farmer, but I can solo most lvl54 AVs. The entire string of those four attacks takes just 6.7 seconds and the damage output is pretty sick, especially since it ends with a superior damage cone +DoT.
I also take energy Torrent which gives me a ranged cone to help with mobs.
