glacial hammer + basic templar defense advice

hi guys,

for 3.1 I want to make a glacial hammer build. please dont respond with "rather use ice crasH", I want to give glacial hammer a go :)

I'd like to know what the best way is to build defenses, as well as dmg.

I'm gonna be doing inquisitor with consecrated ground. and crit makes sense obviously as well for freezing.

For dmg:

1) Are phys damage nodes better than elemental dmg nodes?
2) What about Weapon Elemental Dmg?
3) the cold nodes on the witches side of the tree look appealing, especialyl with the freeze duration etc. worth it?

For defense:

I want to do life regen obviously. I want to have some ES as well so that I utilize the cons ground properly. and armor for dmg reduction.

ie: hybrid defenses. this is viable for templar I assume?

any advice at all on this would be appreciated.

as well as any links to builds you guys have. i've looked at some already but was hoping for more specific advice.

thanks for your time and help in advance!!!! :)
