Staff Sweep Templar Help

Only level 26 as of now and I'm loving this build, but I'm not sure of how it will hold up later into the game.

Right now I'm using Glacial Hammer, Sweep, Decoy Totem, Wrath, and Anger

My current passives at level 26


Was wondering if someone more experienced than me could point me in the right direction of this build.

Some of my questions:
Should I invest into the elemental damage passives?
Area of effect damage and radius, yay or nay?
Should I go deep into defensive trees for armor?
Head North for double curse eventually?
Head South for more health passives + staff or twohander passives?


There are so many attractive options I can't decide where to go.
