Necromancers needs better crit dmg traiting
You should try Dagger/Focus. You also shouldnt underestimate your damage in Death Shroud, compared to the distance of the dagger main-hand the damage is really comparable, it’s even greater if you trait for it to pierce.
If you want AoEs, Staff is actually efficient with power/prec/crit.
Lastly, not sure if you post was toward PvE, sPvP/tPvP and WvW. There a big difference in efficacity.
P.S. you can dodge during the life blast cast (when timed right), making it really efficient.
Dagger/WH, Dagger/Focus, and Axe/Focus, Lich Form, Death shroud. These are all great non-condition types of weapons. In fact we only have on condition style weapon choice adn build. We have multiple ways to do power builds.
In spvp I have 50 crit % and 55 % crit damage. 22k HP. And pretty decent survivability
