Firestorm Templar Build - Need advices.

Hi guys. I've started to play a firestorm templar recently and as far it's working really good, but I have some questions to ask. So, this is my current passive tree (level 63)

What would you change in it? I don't know where should I go at this moment. I think that I need some more damage now, because my HP is 2738 (the armor is a bit low tho, only 830), but I don't see any interesting nodes close to me. For main damage I use Firestorm+faster casting+fire penetration+concentrated effect+life leech (5link) and I have these in a 5link chest. I'm also using fireball+chance to ignite+increased burning dmg+faster casting in my Searing touch. For auras I run purity + clarity.

Here's my gear, tell me please what should I change (I think that the Searing Touch is a bad option atm)

Hey Hey :) ..

I would Play Something Liek That :=)

Try To Get a 5 link Searing Touch Or The Flame Mantle (5L)

High Wand With Spell/Fire/ Mana Reg
