Build optimization on chronomancer hammer of gods (blind build, no guides help) sorry bad English

So i am building around chronomancer with hammer of gods + time snap. Currently level 66 with only second ascendency and managed to do maps tier 6 already with minimal buffs at level 70.

Tried also some t15 maps but got one-shot so i would like your insight on what I'm build defensively, offensively and how ro optimize damage.

I have all elemental and chaos resistances capped + 51% armor , blackbraid fur plate and mahuxotl' shield sitting on 2400 hp + 300 energy shield. Aside from armor what could i improve?

For skills I was thinking to do damage in maps with sismic cry but since it scales damage only with physical i opted for resonating shield with armor break + rage, boneshatter, berserk and herald of ash since the damage scaling is also increased by damage to attacks and not physical only got also an insane attack speed given by the unique amulet that incrases damage and skill speed but reduces elemental resistances ( still capped even with it). I find the damage a little bit low on minions.. how could i improve it?

Sorry for my bad English and thank you in advance for the help!
