Looking for advice on my Earthshatter build

Hi all

This is the first time I make a build by myself, and even thought it's working fine for now, I still want to hear some opinions for more knowledgeable folk than me. I'm currently level 36 and starting Act4. The idea of the build is defending myself with endurance charges, armour and fortify while pumping mace, two-handed and some melee nodes for phys damage, AoE and stun.

Can switch between current and target tree. Intended links are in the notes tab, current ones on the Skill tab.

Any input is appreciated. Thanks in advance.
