PvP Blackout Ranger

I'm currently trying to run a blackout ranger in TA and was wondering if I could get some advice on my current build-

12 marksmanship (9+1+2)
8 Domination
8 Wilderness Survival (7+1)
10 Expertise (9+1, it might be 9 expertise with 8+1)

Punishing Shot {e}
Savage Shot / Distracting Shot
Called Shot (for the frequent touch rangers that I seem to run into)
Read the Wind
Blackout
Whirling Defense
Troll Ungent
Res Sig

I'm thinking about running Dual Shot instead of Called Shot, but I'm not sure, since I could also just use Blackout on any touch ranger instead of having to use an entire skill reserved for that purpose. Then again, it also stops IW warriors from being able to evade, whereas blackout won't stop their dmg.

i say you just run the ol' crip shot ranger with blackout build.

crippling shot [e]/savage shot/apply poison/storm chaser/distortion/blackout/troll ungeunt/rez

14 expertise/10 ws/12 marks/3 illusion/3 domination

touch rangers get rolled by crip shot and blackout, blacking out a warrior takes away his adrenaline, you have lots of stances to get you out of ranger of fat sweaty warriors, and the blackout and degen is nice pressure on the monk. blackout's duration doesn't affect you as much since your prep doesn't disappear. plus, if you ever get into gvg, you'll have more experience as a crip shot ranger.

that should do okay... Always nice rendering them useless before you black them out
