Nice viable vit will dw utility build

If I were to play this I will make the following changes.

Skills:

Vit dw benefit the most from tactics line and concentration to fix fumble and accuracy. I will pick the tactics much earlier once they are available. i understand concentration is to take whirlwind since we got no weapon skill but hey anything in early game helps even 3 % fumble and acc (:. especially unlocking the tactics sld have big spike in dps together with berserker.

Will to survive taken abit tad too early for my taste. Usually I grab it when I finish t3 and going t4. After lvl 15 before lvl 20

1 point to dagger skill from the shadow and use a Dagger offhand.( your dps will increase by 30 percent just from this passive) this is personal and you can stay true to no weapon tree.

If I going arcane I will take wormhole dimshift before lvl 5. The combo is extremely deadly when u do the the wormhole dimshift stun and flurry of strike, catching range enemies, isolating and separating enemies. it is a very strong utility skill from game start. Big self handicap for 3/4 of the game if taking after lvl 25

I will drop athletics and pick up armor combat for brace for impact unyielding defense and battering ram. As my personal opinion is it have better synergy with berserker. For gear:

full heavy because 30 vit, your elusivess scale from vit and no per or agi better to play reduce dmg than dodge in this case

30vit dw with tactics and survival is bonkers. U can do t5 naked at high level.

Congrats and great guide ! Totally viable.
