Switched to Damz but cannot survive

Like many others, played mekunas build first, was breezing through all content, finishing pit 125 fairly easily.

Based on all the reccomendations, made the switch to Damz build to continue pushing further pit while still tackling other content but I can no longer survive anything. Have not been able to survive typical t12 content as I was used to. Can no longer make it through pit 125.

Very confused as to where I went wrong, there is no way this lack of survivability is normal?
