Question about weaver
It depends. The traits offer good damage for thing like a wvw staff ele, and it offers good survivability against power builds from barrier.
Sword is most definately a hybrid that uses condi and power. It has potential as a power weapon but you are losing out on half of your skills potential damage since its all burn/bleed and terrible power scaling.
For staff there is alot of potential for high damage in wvw by going weaver/air/fire.
The superspeed build seems nice in theory but is limited because it locks you out of your attunements for 4 seconds making FA builds not as affective
