My bean ain't Flickering

Hi everyone. First time playing flicker and I'm really struggling to kill bosses and finish my Atlas. Followed Magefist pre league Ignite Bronn's Lithe pob and today watching his update pob, I see he swapped to Farrul's Fur cold flicker. Bossing has been really bad, I know is a "6 portal defense" build but I don't think it is supposed to be this bad, squishiness and lack of frenzy charges are even worse lol. Did Uber lab at lvl 86 because Izaro would one shot me before that. Gave Farrul a shot and could only kill him 2/5 tries

I've assembled mirror builds before (Penance brand of dissipation in Keepers and Heavy Strike of Trarthus str stacker last league) But this one has me beaten.

Any advice I'll appreciate it
