PoE Wintertide curse aura occultist builds

I'm tired of waiting for others to come up with reasonable builds for this skill I love, so I decided to give it a shot myself. I wanted to emphasize slowing enemies as much as I can and the duration of brands. Any discussion on what can be improved on this build is appreciated. Features: Fast clear and death explosions Freedom of mobility for playing brands Cursed and chilled enemies deal 45% less damage with hits (enfeeble & ascendancy) Squishy, but relatively safe from melee, as no melee enemy should be able to touch
