This is my current PVE build, based around On Your Knees. I'm having a blast with it so figured I'd share it. I'm currently W/A, but I'm only using one Assassin skill in this particular build. I'm a relative newb, so if anyone spots anything I could do better, I welcome all advice.

Earth Shaker {E}
Counter Blow
Irresistable Blow
On Your Knees
Berserker Stance
Sprint
Shadow Refuge
Endure Pain

Basically, I use Endure Pain or Endure Pain + Shadow Refuge during the pull to survive any spiking and let my healers get into the swing of things. Berserker to build up adrenaline, and from there, I can keep Berserker and Sprint going pretty much non stop using On Your Knees and the knockdowns from Earth Shaker and Counter Blow. I use Irresistable Blow when someone is blocking / evading a lot or to add in a little extra DPS when needed.

Shadow Refuge can obviously be replaced with anything, it was just a handy anti-degen from what I had available to me.

Very interesting build, but I see that your build is based on DPS.

Here is a suggestion to improve it:

Replace the Beserker's Stance and Sprint with Defensive Stance and Wary Stance. It is much more useful in a group because a warrior's main job is to tank. With the help from On your knees, you can practically always have this stance up, which greatly reduce the threat from melee attackers, along with rangers

Thanks for the advice, and I'll definitely be trying out a variant of this build based around defensive stances instead of offensive stances. Since I'm playing Warrior/Assassin my tanking options are of course limited compared to a Warrior/Monk but there are a couple of interesting defensive skills in the Shadow Arts line.

Actually, i had this here idea:

A W/A with the Shadow step ability.

I think it would help tremendously in pulling, and it would also be a royal pain in the but, as you would never know where you had this 'ere 150 ton Spiky steel death warrior..

Ive not tried it yet, but i know i personnaly would hate it!

Comments? Suggestions? Anything at all, eh?

If you're going to be using On Your Knees, you should be bringing something like Gladiators Defence or something that doesnt end if you use a skill :P.

Seeing as how you have so many KDs, I'd go /Ranger, and replace shadow Refuge with Troll Unguent, you'll get similar regeneration and no change of enchant strip and bring Brambles to get some bleeding and extra damage down. You might be able to fit in apply poison in there for some extra degen.
