1H+S Templar build help

Hello,
I know the basic rule of thumb is that you will screw up your first character, and I think I'm approaching the point very quickly :)
But I thought I would give it a chance to post here and ask the community for some tips and pointers, and if my current build can be saved.

My current Templar build

From the start I built the Templar to be a 1H+S melee caster, focusing on AoE-damage and elemental damage. But then I got distracted by the Zombies, and wanted to make a summoner.
And my main problem at this time is that my zombies just drain my mana, and I feel I'm doing better with out spawning them at all.
Is it worth using the 4 respec points I got, and replace them somewhere else? Or should I remake the character? And do any of you have any tips on building a "Battle Mage"-Templar?
