Thief WvW armor.
I’d throw some PVT in the mix for durability.
What do you want to do in wvw, if all you want to do is roam and catch the other solo’ists then berserker is the way to go.
If you want to be a camp capturer/ scout then I’d suggest a little more hp than berserker so you have more chance for error or to run if a small group comes by to interrupt you,
for actualy running with a zerg I suggest sentinals armor and berzerkers trinkets with fully defenceive masteries. 0-0-30-30-10. I run this with sword/dagger and short bow, I can solo camps, run with any zerg and hug my commander half way through most fights with this build. I can’t always kill someone but I only ever die when I run into the 2 thieve’s +1 mezmer havoc groups.
mix of berserker, val, PVT
Try to get

I have a little more of that stats and works perfectly, of course with foods.
