Welcome to the community!
It gets even better the further into endgame you get 
You can change out the idols was originally converting death seal to physical, but i didnt like spending so many points at the bottom.
Overall your changes all make sense and should work flawlessly.
All these builds are meant to be changed around to the players preferences.
THink of it like a foundational lootfilter that you gotta personalize
Glad to hear your enjoying it
