Backstabbing fun!!!

This is a build that i sort of use during heroics. Its very high short term damage. Big burst. There are three points still available for allocation.

What I do:
If i know there is little chance of being CCed, ill open with cheap shot, hit my prekill buff button (which is my AP trinket, Fury "Orc Racial", Adrenaline Rush), and just spam back stab/Evis till target is dead. And i usually have enough of the madness buff up to take down someone else if there close enough. Most of the time i dont even use the prekill button and still put a good hurt on ppl.

The things to remember on this build is you obviously need to be behind the person. Gouge is your friend. Use it to pool energy back to full. Glyphed Vigor helps alot to get at least 2 back stabs off then a kidney shot... pool up and back stab a few more times and Evis.

If you know your fighting a plate class, its best open then expose armor then disarm and try to burn them down. Just spam backstab while run right at them and past them and spinning around. You almost want to be standing right on them. If you are fighting long enough for overkill to drop off you really need to vanish or stealth as thats a big portion of your energy regen.
Remember to use riposte on melee classes. it can really save your life, its cheap, and it hurts them.

I am a very subpar PVPer but this build works extremely well for me. I am alway usually the top 3 as far as BGs go.

And remember to stack Attack power with this build as all of your crit for backstab comes through talents and gear.
