For P8, HC, I still like blizz
I like it for high damage, Dr, and sorb setup.
Dfathom
Nightwing (facet)
Maras
Vmagi
Mages
Arach
Dwarf/wisp
War Travs/whayeves needed
With a nice inventory and cta, she's top notch on aoe and boss kills.
Merc with infinity is bis, but with cold sunder, it's really ok with insight or reapers.
She handles chaos well, but still no hdin
Light sorc is next, but I don't enjoy her attack style. Nova is fun, but not that strong on p8.
