struggling to get constant rasial kills without dying

Basically I've tried with T90 power gear and I'm getting fucked, wearing thank gear it's going better but I feel like it's way more difficult than it used to be on my main when I first got my rasial set (on necro release), not sure if Rasial got buffed or necro got nerfed but I would appreciate any advice possible.

I can provide further details about my gear or anything needed!
