Hammer Sin - Need help

I've got a Sin build that's half joke half serious, and it's starting to look a little promising. As my lag permits me, I've been testing the build in Isle of the Nameless to see what kind of damage this build is camable of. Here's what I've come up with so far:

Attributes:
Hammer Mastery: 12
Critical Strikes: 12 + 1 + 3
Shadow Arts: 3

Skills:
Crushing Blow
Hammer Bash
Staggering Blow
Mighty Blow
Aura of Displacement {E}
Caltrops
Critical Eye
Res Sig

Armor type: Radiant
Weapons: Vampiric Hammer of Fortitude, PvP Dead Staff

What I've been doing is building up adrenaline off of the AL 100 dummy with the staff, the stepping in on the AL 60 dummy and plastering it with the Hammer skills. When it doesn't lag on me, it's Mighty Blow > Staggering Blow > Hammer Bash > Crushing Blow > Regular hit > Regular hit, and the dummy is dead. I've been able to repeat this, but it just seems way too slow of a buildup and it seems pretty easy to counter.

What I need help with is if anyone knows of a better way of doing this. I'm a bit limited on my Assassin skills, but I've got every Warrior skill from Prophecies and Factions. I've been eyeing some of the Hammer elite skills, but I'd need a different shadow step by that point. Anyone have any insight on this?

if you want a different shadow step skill to free up the elite slot i would take deaths charge also this lacks a self heal and defence.

your better off using the bunny thumper build R/W

Don't need staggering blow... Hammer bash + crushing + irres, or devastating + crushing + fierce.

I say throw in Flurry and Backbreaker so they get KD'd and you can have fun killing them for 4 seconds to build up more adrenaline for some more KD sweetness.
