[POE2] Poison/Chaos damage overtime

Hi all,

Is it me or something it doesn't feel ok with the damage overtime from poison and chaos right now in Poe2.

I've start with a witch wanted to play and essence drain/bain like in poe1 build. But after reaching on level 60 i didnt like it very much, i mean the ascendancy from witch are not made with chaos type in mind... So i've change to a ranger to play a poison build, but even here i am level 20 at the moment with all nodes that boost poison until this level in the tree i am still struggling on bosses, compared to my friends who play other builds...

Is it a issue right now with this build concept or is only in my mind...?!
