Guild Wars 2

I have been playing d/d in wvw with 25/30/0/15 full zerk with good results but found my self dying to randow aoe/attacks and conditions. Today I was playing a s/d w w build(still zerk) with a 10/30/30/0 and threw on a mh dagger and was having more success than all my previous builds.

Is this a popular build in wvw for d/d, or just happened to find my type of play style?

10/30/30 is a very good build. One of my favorites. The shadow arts traits I like to use condition removal on stealth, the 2 point stealth cost reduction, and healing in stealth. This build is very good in long fights and has good synergy with stealth skills like blinding powder and shadow refuge. The extra 300 toughness from shadow arts helps survivability as well.
