Witch Hunter - struggle in Ultimate

Hello Folks,
first of all my GT-link: https://www.grimtools.com/calc/L2JaPDgN

I played this Witch Hunter for about 120 hours now and already started with ultimate.
With this build I went smoothly (most of the time) through Elite. But now in Ultimate it often felt very clunky.

My idea for this build: dual wielding auto-attack with some active skills to buff the auto-attack damage and to get more mobility.

I am greatful for any advices to the build. Even if I have to tear it down and rebuild it from the ground.

Thanks for your time and have nice day

Your resistances sucks. You do not have augments and components in all slots
