why dont you swap on essentia sanguis gloves with mystic harvest ascendancy point with such hight es roll you got ?
made you basically immortal . you also need phy leech on ring to make it work but its really insane
I do have that set up and tried it.
The problem with that is lack of dps. I did t4 simu a ton in the first league too with my invoker and ranger.
You did dps to clear the whole screen very quick. Sustaining is not the answer in there. You get gang banged and stun and they jump on you. No time to sustain.
That glove and passive is great for just regular juiced mapping. But I don't run it since my dmg is very high. Nothing ever gets left on screen
