Eternal rage x vitality x berserk

Can anyone explain to me why havin eternal rage, plus berserk which takes .1% of life per second, and vitality which should generate 1% of life per second does not net in positive life regen? Ive tried vit on multiple different spirit gems and and I still lose life very quickly.

Any assistance would be greatly appreciated!

Omg thank you for that I thought I was going crazy! even after you pointed it out it took me like 4 times of rereading it to comprehend it lol.

u can try going CI with 1 life and just have one regen on ur items. the berserk effect wont kill you
